Description

Technical Field

[0001] The present invention relates to the technical field of heating control, and in particular to a constant temperature heating control method of a heating device for a cooker and a related device. Background Art

[0002] Electric heating equipment is a common electrical appliance in household facilities. Cooking ingredients in pots with electric heating equipment is a common cooking method in every household. In order to prevent the ingredients from burning, constant temperature heating is required after the heating equipment is heated to a certain degree. In the current constant temperature heating control method of heating equipment, the temperature of the cooking pot body is usually detected by a temperature sensor, and the temperature of the heating component is not taken into account. Due to long-term operation, the working temperature of the heating component in the heating equipment increases, making the working state of the heating component unstable, and the working state of the heating component cannot be adjusted in real time according to its working temperature, which makes the temperature of the pot too high, and the food that comes into contact with it is easy to burn, causing sticking to the pot. In addition, the current constant temperature heating method of heating equipment rarely considers the cooking mode of the pot station to select the corresponding constant temperature, resulting in low reliability of the selected constant temperature. When the heating device detects that the current real-time temperature is lower than the set target temperature, the adjustment value of the heating power is usually determined only by calculating the error between the real-time temperature and the target temperature. At the same time, the change in thermal management of the cookware is not taken into consideration. Moreover, due to changes in the internal performance of the components or external disturbances, the constant temperature heating of the heating components will be affected, making it impossible for the constant temperature treatment of the heating device to achieve the desired effect, thereby affecting the taste of the cooked food and causing the pot to stick. Summary of the invention

[0060] During the specific implementation of the present invention, the corresponding station cooking information and cooking food attribute information are determined according to the pot station cooking mode. The station cooking information includes different inclined stations, and different inclined stations correspond to frying modes with different firepower. The station cooking information also includes vertical stations, and the vertical stations correspond to soup making mode and water boiling mode. The cooking food attribute information includes the type, viscosity and weight of the cooking ingredients.

[0061] S13: determining a corresponding target constant temperature based on the cooking information of the workstation and the property information of the food to be cooked;

The database contains appropriate constant temperatures obtained through a large number of experiments, and the corresponding target constant temperature is matched in the database based on the workstation cooking information and the cooking food attribute information.

[0063] S14: obtaining an initial heating power mode using a preset rule library based on the target constant temperature;

[0064] In the specific implementation process of the present invention, after determining the target constant temperature, the corresponding initial heating power mode is determined in the preset rule library according to the corresponding target constant temperature. For example, if the target constant temperature is 200°C, the rated power of the initial heating power control mode is 2000W.

[0067] S16: Determine whether the cooking station information needs to be changed;

[0068] In the specific implementation of the present invention, when controlling the heating component of the heating device to perform heating processing, the user can choose whether to change the cooking station information in the mobile terminal. If so, the process proceeds to step S12, receiving the cooking station change instruction sent by the mobile terminal, determining the new cooking station information according to the cooking station change instruction, such as adjusting the high-fire cooking station to the medium-fire cooking station, determining the new target constant temperature in the cooking parameter set based on the new cooking station information, and generating a heating change instruction based on the new target constant temperature, and transmitting the heating change instruction to the heating device; the heating device generates heating response information based on the heating change instruction, and controls the heating component to perform heating processing again based on the heating response information. If the cooking station information does not need to be changed, the process proceeds to step S17.

[0069] S17: During the heating process of the heating component, detecting a first real-time temperature of the heating component based on a temperature sensor;

[0070] In a specific implementation of the present invention, during the heating process of the heating component, the first real-time temperature of the heating component is detected based on a temperature sensor built in the heating component, and the temperature sensor is attached to the bottom surface of the heating plate of the heating component.

[0071] S18: Determine whether the first real-time temperature is greater than or equal to the target constant temperature;

[0072] In the specific implementation process of the present invention, the first real-time temperature is compared with the target constant temperature. If the first real-time temperature is greater than or equal to the target constant temperature, step S19 is entered. If the first real-time temperature is less than the target constant temperature, step S15 is entered to continue controlling the heating component for heating treatment.

[0073] S19: adjusting the set initial heating power to a preset cooling power;

[0074] During the specific implementation of the present invention, when it is detected that the real-time temperature of the heating component is greater than or equal to the target constant temperature, the initial heating power set according to the target constant temperature is adjusted to a preset cooling power. The preset cooling power may be 0W or a power smaller than the initial heating power. After being adjusted to the preset cooling power, the real-time temperature of the heating component begins to gradually decrease.

[0075] S20: When the heating component is at a preset cooling power, detecting a second real-time temperature of the heating component based on a temperature sensor;

[0076] During the specific implementation of the present invention, when the heating component is at a preset cooling power, the temperature sensor arranged in the heating component will continue to work, and based on the temperature sensor detecting the real-time temperature of the heating component when it is at the preset cooling power, the real-time temperature of the heating component when it is at the preset cooling power is used as the second real-time temperature.

[0077] S21: Determine whether the second real-time temperature is less than the target constant temperature;

[0078] In the specific implementation process of the present invention, the real-time temperature of the heating component when it is at a preset cooling power is compared with the target constant temperature. If it is detected that the real-time temperature is still greater than or equal to the target constant temperature, step S20 is entered to continue to lower the temperature of the heating component based on the preset cooling power. If it is detected that the real-time temperature is lower than the target constant temperature, step S22 is entered.

[0079] S22: calculating the temperature difference between the second real-time temperature and the target constant temperature, and performing numerical simulation based on the temperature difference in combination with a cookware thermal management model to obtain a heating power adjustment coefficient;

[0080] In the specific implementation process of the present invention, the numerical simulation based on the temperature difference combined with the cooker thermal management model is performed to obtain the heating power adjustment coefficient, including: generating the cooker thermal management model based on the cooker attribute information, and establishing a numerical simulation calculation domain based on the cooker thermal management model; constructing a PID control system, and performing numerical simulation based on the PID control system using the temperature difference in combination with the numerical simulation calculation domain to obtain the heating power adjustment coefficient.

[0081] Furthermore, the construction of the PID control system includes: obtaining the object model of the heating component and the cookware thermal management model, calculating the relative order of the object model, and constructing a fractional-order complex network system based on the object model using fractional-order derivatives; constructing an internal model controller based on the relative order using a low-pass filter function; constructing a state error system based on the fractional-order complex network system using a target state equation; and constructing a PID control system based on the internal model controller and the state error system using an extended state observer.

[0082] Specifically, when it is detected that the real-time temperature of the heating component is less than the target constant temperature, the temperature difference between the real-time temperature at the current moment and the target constant temperature is calculated. A pot thermal management model is generated based on the pot attribute information, a reward function of the initial thermal management model is established based on the pot attribute information, the reward function may include a temperature term and a power adjustment term, the thermal management parameters at each historical time point are obtained, the reward value at each time point is calculated according to the reward function and the thermal management parameters at each time point, the future reward value at each time point is calculated according to the reward value at each time point, the sum of future reward values ​​is calculated according to the future reward value at each time point, the initial thermal management model is trained according to the sum of future reward values ​​and the thermal management parameters at each historical time point, the initial thermal management model is a reinforcement learning model, and the pot thermal management model can be obtained. A numerical simulation calculation domain is established based on the pot thermal management model, a thermal management evolution analysis is performed according to the pot thermal management model, and the thermal management evolution analysis results are obtained. The horizontal and vertical ranges of the calculation domain are set according to the thermal management evolution analysis results, and a Boolean subtraction operation is performed according to the horizontal and vertical ranges combined with the thermal management evolution parameters in the thermal management evolution analysis results to obtain the numerical simulation calculation domain. Obtain the object model of the heating component and the pot thermal management model. The object model is an abstraction of the heating component and the pot thermal management model. The decomposed components are taken as the controlled objects. The controlled objects and corresponding functions are abstracted at a preset level to form the corresponding object model. The relative order of the object model is calculated. The preset level of the object model is divided into simpler units. Each unit has a set of corresponding basis functions. The solution vector is calculated according to the basis function. The relative order of the object model can be obtained by geometrically combining and interpolating the solution vector and the basis functions in all units. Based on the object model, a fractional-order complex network system is constructed using fractional-order derivatives, and a differential equation corresponding to the object model is established. The fractional-order order is obtained through the fractional-order derivatives. The fractional-order derivatives are fractional-order derivatives in the sense of Caputo. The fractional-order complex network system is constructed using the corresponding differential equations through the fractional-order orders. Based on the relative order, an internal model controller is constructed using a low-pass filter function. The stability and robustness of the internal model controller are ensured by the low-pass filter function. The addition of the low-pass filter function can make its parameters become adjustable parameters of the internal model controller. The internal model controller can connect the controlled object in parallel to the corresponding loop, so that the output result is closer to the ideal output value. Based on the fractional-order complex network system, a state error system is constructed using the target state equation. The target state equation is constructed. Considering the existence of uncertain and unpredictable nonlinear states, non-periodic orbits and equivalent disturbances for parameters corresponding to the nonlinear state are introduced to construct the target state equation. Based on the target state equation, a state error system between the object model and the fractional-order complex network system is constructed.Based on the internal model controller and the state error system, a proportional-integral-differential (PID) control system is constructed using an extended state observer. The extended state observer regards the uncertainty or interference in the system as one of the states in the system, establishes a new state space, and observes the new state space. The state error system is subjected to an observation system equivalent disturbance by the extended state observer to obtain an extended state vector. The extended state vector is used to obtain an extended state feedback compensation using a preset bandwidth parameter. A PID control system is constructed based on the extended state feedback compensation combined with an internal model controller. Based on the PID control system, a numerical simulation is performed using the temperature difference combined with the numerical simulation calculation domain to obtain a heating power adjustment coefficient. The expression of the heating power adjustment coefficient is:

[0083]

[0084] Where u is the heating power adjustment coefficient, K P is the proportional value calculated by the PID control system, K I is the integral value calculated by the PID control system, K D is the integral value calculated by the PID control system, is the cumulative error, G y is the extended state feedback compensation, and σ is the numerical simulation domain.

[0085] S23: generating a constant temperature heating power based on the heating power adjustment coefficient, and controlling the heating component to perform a constant temperature heating process based on the constant temperature heating power;

[0086] In a specific implementation of the present invention, a constant temperature heating power is obtained by calculating the heating power adjustment coefficient and the heating power of the heating component, and the heating component is controlled to perform constant temperature heating processing based on the constant temperature heating power.

[0087] S24: during the constant temperature heating process of the heating component, obtaining a temperature rise state parameter, and adjusting the constant temperature heating process of the heating component based on the temperature rise state parameter;

[0088] In the specific implementation process of the present invention, the constant temperature heating treatment process of the heating component is adjusted based on the temperature rise state parameters, including: calculating the rising slope and the overshoot based on the temperature rise state parameters; calculating the stable heating duty cycle based on the rising slope and the overshoot; adjusting the stable heating duty cycle based on the target constant temperature to obtain a corrected stable heating duty cycle; the heating component sends a pulse signal based on the corrected stable heating duty cycle, and adjusts the constant temperature heating treatment process of the heating component based on the pulse signal.

[0089] Specifically, the temperature rise state parameter is the real-time temperature at two adjacent time points. The rising slope is calculated using the slope calculation formula according to the real-time temperature at the two adjacent time points. The overshoot is calculated according to the rising slope combined with the preset temperature sensor delay parameter. The temperature sensor delay parameter refers to the delay time or response time of the temperature sensor. The stable heating duty cycle is calculated based on the rising slope and the overshoot. The stable heating duty cycle can be calculated by substituting the rising slope and the overshoot into the preset stable heating duty cycle calculation formula. The stable heating duty cycle is adjusted based on the target constant temperature temperature. According to the relationship between the target constant temperature temperature and the real-time temperature, a correction coefficient is obtained. The stable heating duty cycle is adjusted according to the correction coefficient to obtain a corrected stable heating duty cycle. Based on the corrected stable heating duty cycle, the heating component sends a pulse signal. The pulse signal is used for pulse width modulation to quickly transmit adjustment data in a very short time, and the constant temperature heating process of the heating component is adjusted based on the pulse signal. By using the corrected stable heating duty cycle to adjust the constant temperature heating process of the heating component, the impact of changes in the internal performance of the component or external disturbances is greatly reduced. By correcting the stable heating duty cycle, the error of the constant temperature heating process can be effectively corrected, so that the constant temperature heating control of the heating equipment can achieve a more ideal effect.

[0090] S25: when the heating component is in a constant temperature heating process, detecting the real-time temperature of the heating component in the constant temperature heating process based on a temperature sensor;

[0091] In a specific implementation of the present invention, when the heating component is in a constant temperature heating process, the third real-time temperature of the heating component in the constant temperature heating process is continuously detected based on a temperature sensor built into the heating component.

[0092] S26: Determine whether the real-time temperature of the heating component during the constant temperature heating process is greater than or equal to the target constant temperature.

[0093] In the specific implementation process of the present invention, it is determined whether the real-time temperature of the heating component during the constant temperature heating treatment is greater than or equal to the target constant temperature. If the real-time temperature during the constant temperature heating treatment is greater than or equal to the target constant temperature, step S19 is entered to adjust the heating power to a preset cooling power to reduce the temperature of the heating component. If the real-time temperature during the constant temperature heating treatment is still lower than the target constant temperature, step S22 is entered to calculate the temperature difference between the real-time temperature at each moment and the target constant temperature; based on the temperature difference between the real-time temperature at each moment and the target constant temperature, the heating power adjustment coefficient and the heating state parameters at each moment are updated; and the heating component is subjected to constant temperature heating treatment based on the heating power adjustment coefficient and the heating state parameters at each moment. That is, in this process, the third real-time temperature of the heating component is detected based on the temperature sensor. When the third real-time temperature is still lower than the target constant temperature, the temperature difference is continuously updated, and then the heating power adjustment coefficient is continuously updated to achieve the continuous updating of the heating power. Because the temperature difference changes all the time, the constant temperature heating power is continuously adjusted by continuously updating the temperature difference. When the temperature difference is large, the adjusted constant temperature heating power is large, and when the temperature difference begins to become smaller, the adjusted constant temperature heating power is small, so that rapid heating is achieved and the actual temperature is more easily stabilized. The above processing is repeated to achieve the constant temperature heating control of the heating device until the user cancels the heating. The constant temperature heating control of the heating device achieves a more ideal effect, ensuring that the cooking in the pot will not burn and avoiding the pot sticking phenomenon.

[0094] In the embodiment of the present invention, the corresponding target constant temperature and initial heating power mode are determined by the cooking mode of the pot station, so that the selected target constant temperature can be guaranteed to be more reasonable. And the real-time temperature of the heating component is directly detected by the temperature sensor, so that the working state of the heating component can be adjusted according to the obtained real-time temperature. When it is detected that the real-time temperature of the heating component is lower than the constant temperature taste temperature, the heating power adjustment coefficient is obtained by numerical simulation based on the PID control system using the temperature difference combined with the numerical simulation calculation domain generated by the pot thermal management model, so that the heating power adjustment coefficient that is more in line with the expected situation can be obtained, which solves the hysteresis of the heating power adjustment and can obtain the required heating power adjustment coefficient with faster efficiency. The constant temperature heating process of the heating component is adjusted based on the modified stable heating duty cycle generated by the temperature rise state parameter, which greatly reduces the influence of the change of the internal performance of the component or the external disturbance. The constant temperature control is realized according to the detected real-time temperature of the heating component, so that the constant temperature heating control of the heating equipment achieves a more ideal effect, ensuring that the cooking in the pot will not burn and avoid the phenomenon of sticking to the pot.

[0096] See also Figure 2 , Figure 2 The figure is a schematic diagram of the structural composition of a constant temperature heating control device for a heating device for a cooker in an embodiment of the present invention.

[0097] like Figure 2 As shown, a constant temperature heating control device for a heating device of a cooker, the device comprising:

[0098] Heating component heating processing module 21: used for obtaining a cooking mode of a pot station, determining a corresponding target constant temperature and an initial heating power mode based on the cooking mode of the pot station, and controlling a heating component of a heating device to perform heating processing based on the initial heating power mode;

[0099] In the specific implementation process of the present invention, the corresponding target constant temperature and initial heating power mode are determined based on the cooker station cooking mode, including: determining the corresponding station cooking information and cooking food attribute information based on the cooker station cooking mode; determining the corresponding target constant temperature based on the station cooking information and cooking food attribute information; and obtaining the initial heating power mode based on the target constant temperature using a preset rule library.

[0100] Furthermore, the controlling of the heating component of the heating device to perform heating processing includes: receiving a cooking station change instruction during the process of controlling the heating component of the heating device to perform heating processing, and determining new cooking station information based on the cooking station change instruction; determining a new target constant temperature in a cooking parameter set based on the new cooking station information, and generating a heating change instruction based on the new target constant temperature, and transmitting the heating change instruction to the heating device; the heating device generates heating response information based on the heating change instruction, and controls the heating component to perform heating processing again based on the heating response information.

[0101] Specifically, a pot is placed on a heating device, and the pot is an uncoated pot, such as a stainless steel pot, a titanium pot, and an iron pot. The power of the heating device is turned on, and the heating device is started. The user selects the corresponding pot station cooking mode on the mobile terminal or the control panel. The pot station cooking mode includes a high-fire cooking mode, a medium-fire cooking mode, a low-fire cooking mode, a soup-making mode, and a water-boiling mode. The mobile terminal or the control panel sends the pot station cooking mode instruction selected by the user to the heating device, and the heating device selects the corresponding pot station cooking mode according to the received pot station cooking mode instruction. According to the pot station cooking mode, the corresponding station cooking information and the cooking object attribute information are determined. The station cooking information includes different tilted stations, and different tilted stations correspond to cooking modes with different firepowers. The station cooking information also includes vertical stations, and the vertical stations correspond to soup-making modes and water-boiling modes. The cooking object attribute information includes the type, viscosity, and weight of the cooking ingredients. The corresponding target constant temperature is determined according to the cooking information of the workstation and the attribute information of the food to be cooked. The database contains the appropriate constant temperature obtained through a large number of experiments. The corresponding target constant temperature is matched in the database according to the cooking information of the workstation and the attribute information of the food to be cooked. After determining the target constant temperature, the corresponding initial heating power mode is determined in the preset rule library according to the corresponding target constant temperature. For example, if the target constant temperature is 200°C, the rated power of the initial heating power control mode is 2000W. After determining the corresponding heating power according to the initial heating power control mode, the heating component of the heating device is controlled to perform heating processing according to the corresponding heating power, so as to cook the food in the pot. In the process of controlling the heating component of the heating device to perform heating treatment, the user can choose whether to change the cooking station information on the mobile terminal. If so, the cooking station change instruction sent by the mobile terminal is received, and the new cooking station information is determined according to the cooking station change instruction, such as adjusting the high-fire cooking station to the medium-fire cooking station. Based on the new cooking station information, a new target constant temperature is determined in the cooking parameter set, and a heating change instruction is generated based on the new target constant temperature. The heating change instruction is transmitted to the heating device; the heating device generates heating response information based on the heating change instruction, and controls the heating component to perform heating treatment again based on the heating response information. If the cooking station information does not need to be changed, the heating treatment continues.

[0102] A first real-time temperature detection and comparison module 22: used for detecting a first real-time temperature of the heating component based on a temperature sensor during the heating process of the heating component, and comparing the first real-time temperature with the target constant temperature;

[0103] In the specific implementation of the present invention, during the heating process of the heating component, the first real-time temperature of the heating component is detected based on the temperature sensor built into the heating component, and the temperature sensor is attached to the bottom surface of the heating plate of the heating component. The first real-time temperature is compared with the target constant temperature. If the first real-time temperature is greater than or equal to the target constant temperature, the temperature is lowered. If the first real-time temperature is less than the target constant temperature, the heating component is continued to be controlled to perform the heating process.

[0104] The cooling module 23 is used for adjusting the set initial heating power to a preset cooling power when the first real-time temperature is greater than or equal to the target constant temperature;

[0105] During the specific implementation of the present invention, when it is detected that the real-time temperature of the heating component is greater than or equal to the target constant temperature, the initial heating power set according to the target constant temperature is adjusted to a preset cooling power. The preset cooling power may be 0W or a power smaller than the initial heating power. After being adjusted to the preset cooling power, the real-time temperature of the heating component begins to gradually decrease.

[0106] The second real-time temperature detection module 24 is used to detect the second real-time temperature of the heating component based on the temperature sensor when the heating component is at a preset cooling power;

[0107] In the specific implementation process of the present invention, when the heating component is at the preset cooling power, the temperature sensor provided in the heating component will continue to work, and the real-time temperature of the heating component when it is at the preset cooling power is detected by the temperature sensor, and the real-time temperature of the heating component when it is at the preset cooling power is used as the second real-time temperature. The real-time temperature of the heating component when it is at the preset cooling power is compared with the target constant temperature. If it is detected that the real-time temperature is still greater than or equal to the target constant temperature, the temperature of the heating component is continued to be reduced based on the preset cooling power. If it is detected that the real-time temperature is less than the target constant temperature, the heating power adjustment process is performed.

[0108] A heating power adjustment coefficient generating module 25 is used to calculate the temperature difference between the second real-time temperature and the target constant temperature when it is detected that the second real-time temperature is lower than the target constant temperature, and to perform numerical simulation based on the temperature difference in combination with a cookware thermal management model to obtain a heating power adjustment coefficient;

[0109] In the specific implementation process of the present invention, the numerical simulation based on the temperature difference combined with the cooker thermal management model is performed to obtain the heating power adjustment coefficient, including: generating the cooker thermal management model based on the cooker attribute information, and establishing a numerical simulation calculation domain based on the cooker thermal management model; constructing a PID control system, and performing numerical simulation based on the PID control system using the temperature difference in combination with the numerical simulation calculation domain to obtain the heating power adjustment coefficient.

[0110] Furthermore, the construction of the PID control system includes: obtaining the object model of the heating component and the cookware thermal management model, calculating the relative order of the object model, and constructing a fractional-order complex network system based on the object model using fractional-order derivatives; constructing an internal model controller based on the relative order using a low-pass filter function; constructing a state error system based on the fractional-order complex network system using a target state equation; and constructing a PID control system based on the internal model controller and the state error system using an extended state observer.

[0111] Specifically, when it is detected that the real-time temperature of the heating component is less than the target constant temperature, the temperature difference between the real-time temperature at the current moment and the target constant temperature is calculated. A pot thermal management model is generated based on the pot attribute information, a reward function of the initial thermal management model is established based on the pot attribute information, the reward function may include a temperature term and a power adjustment term, the thermal management parameters at each historical time point are obtained, the reward value at each time point is calculated according to the reward function and the thermal management parameters at each time point, the future reward value at each time point is calculated according to the reward value at each time point, the sum of future reward values ​​is calculated according to the future reward value at each time point, the initial thermal management model is trained according to the sum of future reward values ​​and the thermal management parameters at each historical time point, the initial thermal management model is a reinforcement learning model, and the pot thermal management model can be obtained. A numerical simulation calculation domain is established based on the pot thermal management model, a thermal management evolution analysis is performed according to the pot thermal management model, and the thermal management evolution analysis results are obtained. The horizontal and vertical ranges of the calculation domain are set according to the thermal management evolution analysis results, and a Boolean subtraction operation is performed according to the horizontal and vertical ranges combined with the thermal management evolution parameters in the thermal management evolution analysis results to obtain the numerical simulation calculation domain. Obtain the object model of the heating component and the pot thermal management model. The object model is an abstraction of the heating component and the pot thermal management model. The decomposed components are taken as the controlled objects. The controlled objects and corresponding functions are abstracted at a preset level to form the corresponding object model. The relative order of the object model is calculated. The preset level of the object model is divided into simpler units. Each unit has a set of corresponding basis functions. The solution vector is calculated according to the basis function. The relative order of the object model can be obtained by geometrically combining and interpolating the solution vector and the basis functions in all units. Based on the object model, a fractional-order complex network system is constructed using fractional-order derivatives, and a differential equation corresponding to the object model is established. The fractional-order order is obtained through the fractional-order derivatives. The fractional-order derivatives are fractional-order derivatives in the sense of Caputo. The fractional-order complex network system is constructed using the corresponding differential equations through the fractional-order orders. Based on the relative order, an internal model controller is constructed using a low-pass filter function. The stability and robustness of the internal model controller are ensured by the low-pass filter function. The addition of the low-pass filter function can make its parameters become adjustable parameters of the internal model controller. The internal model controller can connect the controlled object in parallel to the corresponding loop, so that the output result is closer to the ideal output value. Based on the fractional-order complex network system, a state error system is constructed using the target state equation. The target state equation is constructed. Considering the existence of uncertain and unpredictable nonlinear states, non-periodic orbits and equivalent disturbances for parameters corresponding to the nonlinear state are introduced to construct the target state equation. Based on the target state equation, a state error system between the object model and the fractional-order complex network system is constructed.Based on the internal model controller and the state error system, a proportional-integral-differential (PID) control system is constructed using an extended state observer. The extended state observer regards the uncertainty or interference in the system as one of the states in the system, establishes a new state space, and observes the new state space. The state error system is subjected to an observation system equivalent disturbance by the extended state observer to obtain an extended state vector. The extended state vector is used to obtain an extended state feedback compensation using a preset bandwidth parameter. A PID control system is constructed based on the extended state feedback compensation combined with an internal model controller. Based on the PID control system, a numerical simulation is performed using the temperature difference combined with the numerical simulation calculation domain to obtain a heating power adjustment coefficient. The expression of the heating power adjustment coefficient is:

[0112]

[0113] Where u is the heating power adjustment coefficient, K P is the proportional value calculated by the PID control system, K I is the integral value calculated by the PID control system, K D is the integral value calculated by the PID control system, is the cumulative error, G y is the extended state feedback compensation, and σ is the numerical simulation domain.

[0114] Constant temperature heating module 26: used to generate constant temperature heating power based on the heating power adjustment coefficient, and control the heating component to perform constant temperature heating processing based on the constant temperature heating power;

[0115] In the specific implementation process of the present invention, the constant temperature heating treatment of the heating component is controlled based on the constant temperature heating power, including: during the constant temperature heating treatment of the heating component, based on the temperature sensor, detecting the third real-time temperature of the heating component, and before the third real-time temperature is less than the target constant temperature, calculating the temperature difference between the third real-time temperature and the target constant temperature at each moment based on the third real-time temperature; updating the heating power adjustment coefficient and the temperature rise state parameter at each moment based on the temperature difference between the third real-time temperature and the target constant temperature; performing constant temperature heating treatment on the heating component based on the heating power adjustment coefficient and the temperature rise state parameter at each moment; in the third After the real-time temperature is greater than or equal to the target constant temperature, the constant temperature heating power generated by the heating power adjustment coefficient at the current moment is adjusted to the preset cooling power. When the heating component is at the preset cooling power again, the fourth real-time temperature of the heating component is detected based on the temperature sensor; when it is detected that the fourth real-time temperature is lower than the target constant temperature, the temperature difference between the fourth real-time temperature and the target constant temperature is calculated, and a new constant temperature heating power is regenerated based on the temperature difference between the fourth real-time temperature and the target constant temperature. Based on the new constant temperature heating power, the heating component is controlled to perform constant temperature heating processing until the temperature sensor detects that the real-time temperature of the heating component is greater than or equal to the target constant temperature.

[0116] Specifically, when the heating component is in the process of constant temperature heating, the third real-time temperature of the heating component in the process of constant temperature heating is continuously detected based on the temperature sensor built into the heating component. It is determined whether the real-time temperature of the heating component in the process of constant temperature heating is greater than or equal to the target constant temperature. If the real-time temperature in the process of constant temperature heating is greater than or equal to the target constant temperature, the heating power is adjusted to the preset cooling power to reduce the temperature of the heating component. If the real-time temperature in the process of constant temperature heating is still less than the target constant temperature, the temperature difference between the real-time temperature at each moment and the target constant temperature is calculated; based on the temperature difference between the real-time temperature at each moment and the target constant temperature, the heating power adjustment coefficient and the temperature rise state parameter at each moment are updated; based on the heating power adjustment coefficient and the temperature rise state parameter at each moment, the heating component is subjected to constant temperature heating. That is, in this process, the third real-time temperature of the heating component is detected based on the temperature sensor. When the third real-time temperature is still lower than the target constant temperature, the temperature difference is continuously updated, and then the heating power adjustment coefficient is continuously updated to achieve the continuous updating of the heating power. Because the temperature difference changes all the time, the constant temperature heating power is continuously adjusted by continuously updating the temperature difference. When the temperature difference is large, the adjusted constant temperature heating power is large, and when the temperature difference begins to become smaller, the adjusted constant temperature heating power is small, so that rapid heating is achieved and the actual temperature is more easily stabilized. The above processing is repeated to achieve the constant temperature heating control of the heating device until the user cancels the heating. The constant temperature heating control of the heating device achieves a more ideal effect, ensuring that the cooking in the pot will not burn and avoiding the pot sticking phenomenon.

[0117] The constant temperature heating adjustment module 27 is used to obtain the temperature rise state parameter during the constant temperature heating process of the heating component, and adjust the constant temperature heating process of the heating component based on the temperature rise state parameter.

[0118] In the specific implementation process of the present invention, the constant temperature heating treatment process of the heating component is adjusted based on the temperature rise state parameters, including: calculating the rising slope and the overshoot based on the temperature rise state parameters; calculating the stable heating duty cycle based on the rising slope and the overshoot; adjusting the stable heating duty cycle based on the target constant temperature to obtain a corrected stable heating duty cycle; the heating component sends a pulse signal based on the corrected stable heating duty cycle, and adjusts the constant temperature heating treatment process of the heating component based on the pulse signal.

[0119] Specifically, the temperature rise state parameter is the real-time temperature at two adjacent time points. The rising slope is calculated using the slope calculation formula according to the real-time temperature at the two adjacent time points. The overshoot is calculated according to the rising slope combined with the preset temperature sensor delay parameter. The temperature sensor delay parameter refers to the delay time or response time of the temperature sensor. The stable heating duty cycle is calculated based on the rising slope and the overshoot. The stable heating duty cycle can be calculated by substituting the rising slope and the overshoot into the preset stable heating duty cycle calculation formula. The stable heating duty cycle is adjusted based on the target constant temperature temperature. According to the relationship between the target constant temperature temperature and the real-time temperature, a correction coefficient is obtained. The stable heating duty cycle is adjusted according to the correction coefficient to obtain a corrected stable heating duty cycle. Based on the corrected stable heating duty cycle, the heating component sends a pulse signal. The pulse signal is used for pulse width modulation to quickly transmit adjustment data in a very short time, and the constant temperature heating process of the heating component is adjusted based on the pulse signal. By using the corrected stable heating duty cycle to adjust the constant temperature heating process of the heating component, the impact of changes in the internal performance of the component or external disturbances is greatly reduced. By correcting the stable heating duty cycle, the error of the constant temperature heating process can be effectively corrected, so that the constant temperature heating control of the heating equipment can achieve a more ideal effect.

[0120] In the embodiment of the present invention, the corresponding target constant temperature and initial heating power mode are determined by the cooking mode of the pot station, so that the selected target constant temperature can be guaranteed to be more reasonable. And the real-time temperature of the heating component is directly detected by the temperature sensor, so that the working state of the heating component can be adjusted according to the obtained real-time temperature. When it is detected that the real-time temperature of the heating component is lower than the constant temperature taste temperature, the heating power adjustment coefficient is obtained by numerical simulation based on the PID control system using the temperature difference combined with the numerical simulation calculation domain generated by the pot thermal management model, so that the heating power adjustment coefficient that is more in line with the expected situation can be obtained, which solves the hysteresis of the heating power adjustment and can obtain the required heating power adjustment coefficient with faster efficiency. The constant temperature heating process of the heating component is adjusted based on the modified stable heating duty cycle generated by the temperature rise state parameter, which greatly reduces the influence of the change of the internal performance of the component or the external disturbance. The constant temperature control is realized according to the detected real-time temperature of the heating component, so that the constant temperature heating control of the heating equipment achieves a more ideal effect, ensuring that the cooking in the pot will not burn and avoid the phenomenon of sticking to the pot.
