Method, Control Device For Controlling Asynchronous Induction Motor And Motor System

Abstract: The present application relates to motor control technology, in particular to a method for controlling an asynchronous induction motor, a control device for implementing the method, a motor system including the control device, and a computer-readable storage medium on which a computer program for implementing the method is stored. The method for controlling the asynchronous induction motor according to some embodiments of the application comprises: A. determining a target value of d-axis current according to a target value of q-axis current of the asynchronous induction motor; B. determining a correction value of the target value of the d-axis current based on q-axis voltage and d-axis voltage of the asynchronous induction motor; and C. determining target values of the d-axis voltage and the q-axis voltage of the asynchronous induction motor based on the correction value of the target value of the d-axis current and the target value of the q-axis current. In the above embodiment, through the feedback mechanism based on voltage amplitude, the flux current can be controlled adaptively, and the motor efficiency can be improved without sacrificing torque performance. In addition, because the control logic does not involve motor parameters, it has strong robustness.
