Electronic device with voice-controlling function and voice-controlling method

The invention provides an electronic device with a voice-controlling function, which comprises a storage unit, a sound-receiving unit, an instruction-analyzing unit, a processing unit and a logic-analyzing module, wherein the storage unit is used for storing a preset voice signal and the corresponding relation of the preset voice signal and a control instruction. The sound-receiving unit is used for receiving the voice signal of a user. The instruction-analyzing unit is used for comparing and analyzing the voice signal of the user and the preset voice signal and determining the corresponding control instruction. The processing unit is used for executing a function corresponding to the control instruction and storing the historical control instruction. The logic-analyzing module is used for determining the control instruction with the largest probability by combining the stored historical control instruction and the current working state of the electronic device when the voice signal of the user and the preset voice signal are analyzed to be not in unique correspondence by the instruction-analyzing unit, and the processing unit is used for executing the corresponding function according to the control instruction. The invention also provides a voice-controlling method. Through the invention, the electronic device with the voice-controlling function is more intellectualized, so that the use of the user is facilitated.

Networked servomotor control method based on disturbance observer

The invention provides a networked servomotor control method based on a disturbance observer. According to the method, a measuring element acquires the angular displacement and angular velocity of a servomotor and sends the angular displacement and the angular velocity to the disturbance observer and a sliding mode controller through a network, the disturbance observer simultaneously reads historical control quantity values, stored in a control quantity buffer, and estimates a disturbance size and sends the disturbance size to the sliding mode controller, and the sliding mode controller obtains a control voltage signal through solving and sends the control voltage signal to the servomotor through the network so as to form closed-loop network control on the servomotor. The method is applied to a servomotor system with external disturbance, and the networked control is realized through network connection, so that the interoperability, flexibility and the like of the system are improved; through selecting a sliding mode function with historical control input, the network-induced time delay is compensated, and the stability of the system is improved; and through designing the disturbance observer, the disturbance suppression is realized, the buffeting of the system is reduced, and the dynamic performance of the system is improved.

Method and device for controlling energy storage system, energy storage system and power system

The invention relates to a method and a device for controlling an energy storage system, an energy storage system and a power system. The method includes the following steps: receiving a current powergrid dispatching instruction, and determining the minimum limit power according to the current power grid dispatching instruction and preset first control parameters; acquiring the current output value of a generator set and the historical control parameters in a first preset historical period, and obtaining a first predicted value of power according to the current output value and the historicalcontrol parameters; determining target control parameters according to the minimum limit power and the first predicted value of power; and acquiring a target output value of the energy storage systemaccording to the target control parameters, and making the energy storage system output electric energy according to the target output value. Thus, when the energy storage system and the generator set cannot respond to the power grid dispatching instruction, the target output value of the energy storage system can be flexibly adjusted so that the combined output value of the energy storage systemand the generator set can meet the dispatching demand of the power grid side.

Control method, device and equipment for distributed control system and medium

The invention discloses a control method for a distributed control system. The control method comprises the following steps: acquiring historical operation data of a unit; according to the historicaloperation data, establishing a corresponding relationship between the actual output quantity and the historical control parameters under different historical conditions; searching a corresponding target historical control parameter when the target condition is consistent with the historical condition and the actual output is the target output according to the corresponding relationship, and takingthe target historical control parameter as a current control parameter; and generating a control instruction according to the current control parameter, and sending the control instruction to a distributed control system of the unit. Therefore, the setting process of human intervention control parameters is avoided, and time resources and human resources are greatly saved; moreover, the setting accuracy of the control parameters is improved, and the requirements of an operator are better met. In addition, the control device and equipment for the distributed control system and the storage medium provided by the invention correspond to the method.
