Technical Field

[0001] This application relates to the field of smart homes, and more particularly to a method, apparatus, device, and storage medium for controlling a clothes drying device. Background Technology

[0002] With the development of computer technology and smart home technology, the application of clothes drying equipment is becoming increasingly widespread. Clothes drying equipment is usually equipped with adjustable drying rods, such as the ability to lower the rod for convenient hanging of clothes and raise it for better drying.

[0003] Clothes drying equipment can be equipped with multiple drying rods to increase the capacity for drying clothes. However, since the weight of clothes on different drying rods is different, the uneven load on the different drying rods can cause them to shift when controlling the raising and lowering of multiple drying rods. Summary of the Invention

It can maintain the synchronous movement of multiple drying racks, reduce the problem of drying rack deviation due to uneven load, and improve the control effect of the drying rack.

Detailed Implementation

[0012] To make the objectives, technical solutions, and advantages of this application clearer, specific embodiments of this application will be described in further detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely for explaining this application and not for limiting it. It should also be noted that, for ease of description, only the parts relevant to this application are shown in the drawings, not all of them. Before discussing exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe operations (or steps) as sequential processes, many of these operations can be performed in parallel, concurrently, or simultaneously. Furthermore, the order of the operations can be rearranged. The process can be terminated when its operation is completed, but additional steps not included in the drawings may also be present. The above processes can correspond to methods, functions, procedures, subroutines, subroutines, etc.

[0013] In the control schemes of related drying equipment, motors are generally controlled based on a fixed duty cycle. However, in actual use, the weight of clothes on different drying rods may vary, leading to inconsistent lifting and lowering speeds and deviations in the cumulative travel of the rods. This results in misalignment between the rods (e.g., inconsistent lifting and lowering speeds and heights), causing significant confusion for users. Therefore, this application provides a drying equipment control method to solve the aforementioned technical problems.

[0014] Figure 1 A flowchart of a control method for a clothes drying device provided in an embodiment of this application is provided. The control method for a clothes drying device provided in this application can be executed by a control device for the clothes drying device. The control device for the clothes drying device can be implemented by hardware and / or software and integrated into the clothes drying device (e.g., a clothes dryer).

[0015] The following description uses the control device for the drying equipment as an example to illustrate the control method for the drying equipment. (Reference) Figure 1 The control method for this drying equipment includes: S110: When at least two motors used to drive the lifting and lowering of the drying rack of the drying equipment are in operation, determine the actual operating parameters of at least two motors, including the actual operating frequency and / or the actual operating speed.

[0016] The drying equipment provided in this application includes multiple independently height-adjustable drying rods and multiple motors for driving the lifting and lowering of each drying rod. The lifting and lowering of each drying rod can be controlled by one or more motors. The forward or reverse rotation of the motor can control the rise or fall of the corresponding drying rod, and the rising or falling speed of the corresponding drying rod can be controlled by changing the operating parameters of the motor. The operating parameters of the motor can be adjusted through the motor control parameters. These operating parameters include operating frequency and / or operating speed, and the control parameter can be the duty cycle, which can be set using a pulse width modulation signal (PWM signal).

[0017] The drying racks can be used for drying clothes. For example, the drying racks can be horizontally placed rods on clothes drying machines, allowing users to hang clothes racks on them or place clothes directly on them. When users need to dry clothes, they can control one or more drying racks to descend to a preset height or a user-specified height via a control panel, control buttons, or remote control devices (such as remote controls or mobile phones). Users can then hang clothes on the drying racks and control the racks to rise to the preset or user-specified height for drying. When users need to collect clothes, they can control one or more drying racks to descend to the preset or user-specified height, remove the clothes from the racks, and then control the racks to rise to the preset or user-specified height.

[0018] In one embodiment, the raising and lowering of a single drying rack can be controlled, or the raising and lowering of at least two drying racks can be controlled. In order to reduce the occurrence of misalignment between different drying racks, it is necessary to control the synchronous operation (e.g., synchronous raising and lowering) of at least two drying racks based on the drying equipment control method to improve the control effect of the drying equipment.

[0019] For example, the system monitors in real time whether each motor is running, and when at least two motors are detected to be running, the duty cycle of the running motors is set to the default duty cycle. The actual duty cycle of the running motors is monitored, and when the actual duty cycles of all running motors reach the default duty cycle, the actual operating parameters of at least two motors (i.e., the motors currently running) are monitored in real time. Specifically, when the drying equipment is powered on, a default duty cycle can be set for each motor. This default duty cycle can be the maximum duty cycle of the motor, or it can be set to a value lower than the maximum duty cycle.

[0020] In this configuration, when the motor is running, it drives the corresponding drying rack to rise and fall; when the motor is not running (i.e., stopped), the corresponding drying rack remains stationary. In one embodiment, when all motors are stopped, or when only one drying rack is running, the motor control parameters do not need to be adjusted. Optionally, the motor's operating frequency can be represented by the frequency of the motor's Hall waveform (in this case, the motor is a Hall motor), and the operating speed can be represented by the motor's rotor speed.

[0021] S120: Determine the difference in operating parameters between the actual operating parameters of at least two motors.

[0022] For example, the differences in operating parameters between the actual operating parameters of the at least two motors are determined. These differences include frequency differences between the actual operating frequencies of the motors, and / or speed differences between their actual operating speeds.

[0023] In one embodiment, when at least two motors are two motors, the difference in operating parameters between the actual operating parameters of the two motors can be determined, such as the frequency difference between the actual operating frequencies of the two motors, and / or the speed difference between the actual operating speeds.

[0024] In one embodiment, when there are at least two motors, the difference in operating parameters between the maximum and minimum actual operating parameters among the multiple motors can be determined, such as the frequency difference between the maximum and minimum actual operating frequencies among the multiple motors, and / or the speed difference between the maximum and minimum actual operating speeds.

[0025] S130: If the difference in operating parameters does not meet the preset synchronization judgment condition, adjust the control parameters of at least one motor until the difference in operating parameters meets the synchronization judgment condition.

[0026] For example, it is determined whether the difference in operating parameters meets the preset synchronization judgment condition. When the difference in operating parameters meets the preset synchronization judgment condition, the control parameters of the motors in operation determined above can be maintained to maintain the synchronous movement of the drying racks corresponding to the at least two motors.

[0027] The synchronization judgment conditions provided in this application can be used to determine whether at least two motors in operation are in a synchronized state. For example, when the difference in operating parameters between at least two motors in operation is within a preset difference threshold range, the difference in operating parameters can be considered to meet the preset synchronization judgment conditions; when the difference in operating parameters between at least two motors in operation is outside the preset difference threshold range, the difference in operating parameters can be considered to not meet the preset synchronization judgment conditions.

[0028] The difference threshold range may include the frequency difference range and / or the speed difference range. For example, if the frequency difference between the actual operating frequencies of at least two motors in operation exceeds the frequency difference range, and / or the speed difference between the actual operating speeds exceeds the speed difference range, the difference in operating parameters is considered not to meet the preset synchronization judgment condition.

[0029] In one embodiment, when it is determined that the difference in operating parameters does not meet a preset synchronization judgment condition, the control parameters of at least one of the at least two motors are adjusted. The actual operating parameters of the at least two motors are continuously acquired, and the difference in operating parameters between the actual operating parameters of the at least two motors is updated in real time. If the updated difference in operating parameters still does not meet the preset synchronization judgment condition, the control parameters of at least one motor are adjusted until the difference in operating parameters meets the synchronization judgment condition.

[0030] Optionally, adjusting the control parameters of at least one motor can involve fixing the control parameters of one motor in operation and adjusting the control parameters of the other motors in operation so that the actual operating parameters of the other motors in operation approach the actual operating parameters of the motor with the fixed control parameters. For example, fixing the duty cycle of one motor in operation and adjusting the duty cycles of the other motors in operation so that the actual operating frequency and / or actual operating speed of the other motors in operation approach the actual operating frequency and / or actual operating speed of the motor with the fixed duty cycle.

[0031] In one embodiment, adjusting the control parameters of at least one motor can also involve simultaneously adjusting the control parameters of each motor in operation to bring the actual operating parameters of each motor in operation closer to preset operating parameters (e.g., the average operating parameters of multiple motors in operation). For example, adjusting the control parameters of at least one motor can also involve simultaneously adjusting the duty cycle of each motor in operation to bring the actual operating frequency and / or actual operating speed of each motor in operation closer to preset operating frequency and / or preset operating speed (e.g., the average operating frequency and / or average operating speed of multiple motors in operation).

[0032] The above-mentioned method involves determining the actual operating parameters of at least two motors that drive the lifting and lowering of the drying racks of the drying equipment when they are in operation, and determining the difference between the actual operating parameters of the at least two motors. If the difference between the operating parameters does not meet the preset synchronization judgment condition, the control parameters of at least one motor are adjusted until the difference between the operating parameters meets the synchronization judgment condition, so that at least two drying racks keep running synchronously, reducing the problem of drying rack deviation caused by uneven load on different drying racks, and effectively improving the control effect of the drying equipment.

[0033] Based on the above embodiments, Figure 2 A flowchart of another control method for a drying device provided in an embodiment of this application is given, which is a concretization of the above-described control method for a drying device. (Reference) Figure 2 The control method for this drying equipment includes: S210: When at least two motors used to drive the raising and lowering of the drying rack of the drying equipment are in operation, determine the actual operating parameters of at least two motors, including the actual operating frequency and / or the actual operating speed.

[0034] S220: Determine the difference in operating parameters between the actual operating parameters of at least two motors.

[0035] S230: When the difference in operating parameters does not meet the preset synchronization judgment conditions, determine the minimum actual operating parameter among the actual operating parameters of at least two motors.

[0036] S240: With the minimum actual operating parameters as the target, adjust the duty cycle of motors other than the motor corresponding to the minimum actual operating parameters until the difference in operating parameters meets the synchronization judgment condition.

[0037] For example, when the difference in operating parameters does not meet the preset synchronization judgment condition, the minimum actual operating parameter is determined among the actual operating parameters of at least two motors. Using the minimum actual operating parameter as the target, the duty cycle of the motors other than the one corresponding to the minimum actual operating parameter is adjusted until the difference in operating parameters meets the synchronization judgment condition. For instance, the minimum actual operating parameter can be used as the target operating parameter for the motor controller. The controller will adaptively control the duty cycle with the minimum actual operating parameter as the target, thereby adjusting the actual operating parameters of the corresponding motor so that the actual operating parameters of the corresponding motor approach the minimum actual operating parameter.

[0038] The minimum actual operating parameters include the minimum actual operating frequency and / or the minimum actual operating speed. For example, the minimum actual operating frequency and / or the minimum actual operating speed can be used as the target frequency and / or target speed of the motor controller. The controller will adaptively control the duty cycle of the PWM signal sent to the corresponding motor with the minimum actual operating frequency and / or the minimum actual operating speed as the target, thereby adjusting the actual operating frequency and / or the actual operating speed of the corresponding motor. This will bring the actual operating frequency and / or the actual operating speed of the corresponding motor closer to the minimum actual operating frequency and / or the minimum actual operating speed, until the frequency difference between the actual operating frequency and the minimum actual operating frequency is within a preset frequency difference range, and / or the speed difference between the actual operating speed and the minimum actual speed is within a preset speed difference range. At this point, the difference in operating parameters satisfies the synchronization judgment condition.

[0039] This application adjusts the duty cycle of other motors by targeting the minimum actual operating parameter among the actual operating parameters of at least two motors when the difference in operating parameters does not meet the preset synchronization judgment condition. This causes the difference in operating parameters of other motors to change in the direction of meeting the synchronization judgment condition, thereby enabling at least two motors to quickly enter a synchronized operating state by reducing the operating parameters.

[0040] In one possible embodiment, the drying equipment control method provided in this application, after adjusting the duty cycle of motors other than the motor corresponding to the minimum actual operating parameters, further includes: S250: If the duty cycle of a motor other than the motor corresponding to the minimum actual operating parameter is adjusted to be less than or equal to the preset duty cycle threshold, and the difference in operating parameters still does not meet the synchronization judgment condition, the maximum actual operating parameter is determined from the actual operating parameters of at least two motors.

[0041] S260: Adjust the duty cycle of motors other than the motor corresponding to the maximum actual operating parameter, with the maximum actual operating parameter as the target.

[0042] For example, after adjusting the duty cycle of motors other than those corresponding to the minimum actual operating parameters, the duty cycle of each motor is detected in real time, and it is determined whether the duty cycle of each motor has been adjusted to be less than or equal to a preset duty cycle threshold. Optionally, the preset duty cycle threshold can be a pre-set default duty cycle.

[0043] If the duty cycle of motors other than those corresponding to the motor with the minimum actual operating parameter is adjusted to be less than or equal to a preset duty cycle threshold, and the difference in operating parameters still does not meet the synchronization judgment condition, then the maximum actual operating parameter is determined from the actual operating parameters of the motors currently in operation. Using this maximum actual operating parameter as the target, the duty cycle of motors other than those corresponding to the maximum actual operating parameter is adjusted until the difference in operating parameters meets the synchronization judgment condition. For example, if the maximum actual operating parameter is used as the target operating parameter for the motor controller, the controller will adaptively control the duty cycle with the maximum actual operating parameter as the target, thereby adjusting the actual operating parameters of the corresponding motor to bring them closer to the maximum actual operating parameter.

[0044] The maximum actual operating parameters include the maximum actual operating frequency and / or the maximum actual operating speed. For example, the maximum actual operating frequency and / or the maximum actual operating speed can be used as the target frequency and / or target speed of the motor controller. The controller will adaptively control the duty cycle of the PWM signal sent to the corresponding motor with the maximum actual operating frequency and / or the maximum actual operating speed as the target, thereby adjusting the actual operating frequency and / or the actual operating speed of the corresponding motor. This will make the actual operating frequency and / or the actual operating speed of the corresponding motor approach the maximum actual operating frequency and / or the maximum actual operating speed, until the frequency difference between the actual operating frequency and the maximum actual operating frequency is within a preset frequency difference range, and / or the speed difference between the actual operating speed and the maximum actual speed is within a preset speed difference range. At this point, the difference in operating parameters satisfies the synchronization judgment condition.

[0045] This application adjusts the duty cycle of the motor with the minimum actual operating parameters as the target. When the duty cycle of the motor is adjusted to be less than or equal to the preset duty cycle threshold, but the synchronization judgment condition still cannot be met, the duty cycle of other motors is adjusted with the maximum actual operating parameter among the actual operating parameters of at least two motors as the target. This makes the difference in the operating parameters of other motors change in the direction of meeting the synchronization judgment condition. By increasing the operating parameters, it ensures that at least two motors enter the synchronous operation state more quickly.

[0046] In one possible embodiment, the drying equipment provided in this application is a double-pole drying equipment, and correspondingly, at least two motors include a first motor and a second motor. Based on this, the drying equipment control method provided in this application determines the difference in operating parameters between the actual operating parameters of the at least two motors by subtracting the actual operating parameters of the first motor and the actual operating parameters of the second motor, and determining the difference in operating parameters as the result of the subtraction.

[0047] In one embodiment, if the difference in operating parameters is greater than or less than a preset difference threshold, it can be considered that the difference in operating parameters does not meet the preset synchronization judgment condition. For example, taking the actual operating frequency as the actual operating parameter, the actual operating frequency f1 of the first motor and the actual operating frequency f2 of the second motor are detected. The difference between the actual operating frequencies f1 and f2 is subtracted to obtain the difference in operating parameters between the first motor and the second motor, Δf = f1 - f2. It is then determined whether the difference in operating parameters Δf is greater than or less than the preset difference threshold. ref When the difference in operating parameters Δf > the preset difference threshold f ref Or the difference in operating parameters Δf is less than the preset difference threshold f ref When the difference in operating parameters does not meet the preset synchronization judgment condition, it can be determined that the difference in operating parameters Δf = the preset difference threshold f. refWhen the difference in operating parameters meets the preset synchronization judgment condition, it can be determined that the difference is sufficient. The preset difference threshold f is... ref It can be set to 0.

[0048] When there are two motors, including a first motor and a second motor, this application uses the difference between the actual operating parameters of the first motor and the actual operating parameters of the second motor as the difference in operating parameters. This accurately reflects the synchronous operation status between the first motor and the second motor, and can more accurately determine whether the difference in operating parameters meets the preset synchronous judgment conditions, thereby improving the control accuracy of the drying equipment.

[0049] In one embodiment, the control method for the drying equipment provided in this application adjusts the control parameters of at least one motor, which may be as follows: when the difference in operating parameters is greater than a preset difference threshold, the duty cycle of the first motor is adjusted with the actual operating parameters of the second motor as the target; when the difference in operating parameters is less than the preset difference threshold, the duty cycle of the second motor is adjusted with the actual operating parameters of the first motor as the target.

[0050] For example, when the difference in operating parameters exceeds a preset difference threshold, the duty cycle of the first motor is adjusted with the actual operating parameters of the second motor as the target, until the difference in operating parameters between the first and second motors meets the synchronization judgment condition. For instance, the actual operating parameters of the second motor are used as the target operating parameters of the controller for the first motor. The controller will adaptively control the duty cycle of the first motor with the actual operating parameters of the second motor as the target, thereby adjusting the actual operating parameters of the first motor to bring them closer to the actual operating parameters of the second motor.

[0051] The actual operating parameters include the actual operating frequency and / or actual operating speed. For example, the actual operating frequency and / or actual operating speed of the second motor can be used as the target frequency and / or target speed of the controller of the first motor. The controller will adaptively control the duty cycle of the PWM signal sent to the first motor with the actual operating frequency and / or actual operating speed of the second motor as the target, thereby adjusting the actual operating frequency and / or actual operating speed of the first motor so that the actual operating frequency and / or actual operating speed of the first motor is closer to the actual operating frequency and / or actual operating speed of the second motor, so that the difference in operating parameters is closer to the direction that satisfies the synchronization judgment condition.

[0052] In one embodiment, when the difference in operating parameters is less than a preset difference threshold, the duty cycle of the second motor is adjusted with the actual operating parameters of the first motor as the target, until the difference in operating parameters between the first and second motors meets the synchronization judgment condition. For example, the actual operating parameters of the first motor are used as the target operating parameters of the controller for the second motor. The controller will adaptively control the duty cycle of the second motor with the actual operating parameters of the first motor as the target, thereby adjusting the actual operating parameters of the second motor so that the actual operating parameters of the second motor are closer to those of the first motor.

[0053] The actual operating parameters include the actual operating frequency and / or actual operating speed. For example, the actual operating frequency and / or actual operating speed of the first motor can be used as the target frequency and / or target speed of the controller of the second motor. The controller will adaptively control the duty cycle of the PWM signal sent to the second motor with the actual operating frequency and / or actual operating speed of the first motor as the target, thereby adjusting the actual operating frequency and / or actual operating speed of the second motor so that the actual operating frequency and / or actual operating speed of the second motor is closer to the actual operating frequency and / or actual operating speed of the first motor, so that the difference in operating parameters is closer to the direction that satisfies the synchronization judgment condition.

[0054] This application adjusts the duty cycle of the other motor by taking the minimum actual operating parameter of the two motors as the target when the difference in operating parameters does not meet the preset synchronization judgment condition. This causes the difference in operating parameters of the other motor to change in the direction of meeting the synchronization judgment condition, thereby enabling the two motors to quickly enter a synchronized operating state by reducing the operating parameters.

[0055] In one possible embodiment, the drying equipment control method provided in this application, after adjusting the duty cycle of the first motor, further includes: when the duty cycle of the first motor is adjusted to be less than or equal to a preset duty cycle threshold, and the difference in operating parameters still does not meet the preset synchronization judgment condition, adjusting the duty cycle of the second motor with the actual operating parameters of the first motor as the target. If the duty cycle of the second motor is adjusted to be less than or equal to the preset duty cycle threshold, but the difference in operating parameters still does not meet the preset synchronization judgment condition, the duty cycle of the first motor is adjusted with the actual operating parameters of the second motor as the target.

[0056] For example, after adjusting the duty cycle of the first motor with the actual operating parameters of the second motor as the target, if the difference in operating parameters still does not meet the preset synchronization judgment condition after adjusting the duty cycle of the first motor to be less than or equal to the preset duty cycle threshold, then the duty cycle of the second motor is adjusted with the actual operating parameters of the first motor as the target.

[0057] For example, if the current actual operating frequency and / or actual operating speed of the first motor is used as the target frequency and / or target speed of the controller of the second motor, the controller will adaptively control the duty cycle of the PWM signal sent to the second motor with the current actual operating frequency and / or actual operating speed of the first motor as the target, thereby adjusting the actual operating frequency and / or actual operating speed of the second motor so that the actual operating frequency and / or actual operating speed of the second motor approaches the current actual operating frequency and / or actual operating speed of the first motor.

[0058] In one embodiment, after adjusting the duty cycle of the second motor with the actual operating parameters of the first motor as the target, if the difference in operating parameters still does not meet the preset synchronization judgment condition after adjusting the duty cycle of the second motor to be less than or equal to the preset duty cycle threshold, then the duty cycle of the first motor is adjusted with the actual operating parameters of the second motor as the target.

[0059] For example, if the current actual operating frequency and / or actual operating speed of the second motor is used as the target frequency and / or target speed of the controller of the first motor, the controller will adaptively control the duty cycle of the PWM signal sent to the first motor with the current actual operating frequency and / or actual operating speed of the second motor as the target, thereby adjusting the actual operating frequency and / or actual operating speed of the first motor so that the actual operating frequency and / or actual operating speed of the first motor approaches the current actual operating frequency and / or actual operating speed of the second motor.

[0060] This application adjusts the duty cycle of the motor with the actual operating parameters as the target. When the duty cycle of the motor is adjusted to be less than or equal to the preset duty cycle threshold, but the synchronization judgment condition still cannot be met, the duty cycle of the other motor is adjusted with the maximum actual operating parameter of the two motors as the target. This makes the difference in the operating parameters of the other motor change in the direction of meeting the synchronization judgment condition. By increasing the operating parameters, the two motors are ensured to enter the synchronous operation state more quickly.

[0061] The above-described method involves determining the actual operating parameters of at least two motors, each driving the lifting and lowering of the drying racks, when they are in operation. It also determines the difference between these actual operating parameters. If the difference in operating parameters does not meet a preset synchronization condition, the control parameters of at least one motor are adjusted until the difference satisfies the synchronization condition. This ensures that the at least two drying racks operate synchronously, reducing the problem of rack misalignment due to uneven load and effectively improving the control performance of the drying equipment. Furthermore, when the difference in operating parameters does not meet the preset synchronization condition, the duty cycle of other motors is adjusted with the minimum actual operating parameter among the at least two motors as the target. This causes the difference in operating parameters of other motors to change in the direction that satisfies the synchronization condition, thereby reducing the operating parameters and enabling the at least two motors to quickly enter a synchronous operating state.

(Reference) Figure 3 The control device for the drying equipment includes a motor detection module 31, a difference analysis module 32, and a parameter adjustment module 33.

[0063] The motor detection module 31 is used to determine the actual operating parameters of at least two motors, including the actual operating frequency and / or actual operating speed, when at least two motors that drive the lifting and lowering of the drying rack of the drying equipment are in operation. The difference analysis module 32 is used to determine the difference in operating parameters between the actual operating parameters of at least two motors. The parameter adjustment module 33 is used to adjust the control parameters of at least one motor until the difference in operating parameters meets the preset synchronization judgment condition when the difference in operating parameters does not meet the preset synchronization judgment condition.

[0064] The above-mentioned method involves determining the actual operating parameters of at least two motors that drive the lifting and lowering of the drying racks of the drying equipment when they are in operation, and determining the difference between the actual operating parameters of the at least two motors. If the difference between the operating parameters does not meet the preset synchronization judgment condition, the control parameters of at least one motor are adjusted until the difference between the operating parameters meets the synchronization judgment condition, so that at least two drying racks keep running synchronously, reducing the problem of drying rack deviation caused by uneven load on different drying racks, and effectively improving the control effect of the drying equipment.

[0065] In one possible embodiment, the parameter adjustment module 33 adjusts the control parameters of at least one motor, including: Determine the minimum actual operating parameter from at least two actual operating parameters of the motor; With the goal of achieving the minimum actual operating parameters, adjust the duty cycle of motors other than the motor corresponding to the minimum actual operating parameters.

[0066] In one possible embodiment, after adjusting the duty cycle of motors other than the motor corresponding to the minimum actual operating parameter, the parameter adjustment module 33 further includes: If the duty cycle of motors other than the motor corresponding to the minimum actual operating parameter is adjusted to be less than or equal to the preset duty cycle threshold, and the difference in operating parameters still does not meet the synchronization judgment condition, the maximum actual operating parameter is determined from the actual operating parameters of at least two motors. With the maximum actual operating parameters as the target, adjust the duty cycle of motors other than the motor corresponding to the maximum actual operating parameters.

[0067] In one possible embodiment, at least two motors include a first motor and a second motor; The difference analysis module 32 determines the differences in operating parameters between the actual operating parameters of at least two motors, including: Subtract the actual operating parameters of the first motor from the actual operating parameters of the second motor, and determine the difference in operating parameters by the result of the subtraction.

[0069] In one possible embodiment, the parameter adjustment module 33 adjusts the control parameters of at least one motor, including: If the difference in operating parameters exceeds the preset difference threshold, the duty cycle of the first motor is adjusted based on the actual operating parameters of the second motor. If the difference in operating parameters is less than a preset difference threshold, the duty cycle of the second motor is adjusted based on the actual operating parameters of the first motor.
