Title:
METHOD FOR CONTROLLING MOTOR, CONTROL SYSTEM, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/237828
Kind Code:
A1
Abstract:
Provided is a method for controlling a motor, the method comprising: sequentially executing a Clarke transform and a Park transform on an inputted three-phase input current of a motor, and acquiring a feedback current vector in a rotor dq coordinate system; executing decoupling on an inputted command current vector of the motor in the rotor dq coordinate system and the feedback current vector in the rotor dq coordinate system, and determining a processed voltage as a voltage vector in the rotor dq coordinate system; sequentially executing inverse Park transforms on the voltage vector in the rotor dq coordinate system; performing SVPWM modulation so as to obtain a PWM pulse wave; and inputting the PWM pulse wave into an inverter, and acquiring an input voltage of the motor so as to control the motor. Also provided are a control system and a storage medium.
