Abstract
Disclosed is a measurement and control method, device, and electronic equipment for motor current and speed. The method comprises: obtaining an input speed and an input current, obtaining a motor measurement and control model, inputting the input speed and the input current into a motor measurement and control model for measurement operation to obtain a current motor speed, obtaining a motor explicit control rate, and conducting a current calculating based on the current motor speed and the input speed under the motor explicit control rate to obtain a reference current; conducting a current calculating based on the reference current and the input current to obtain a current value of the current, and controlling the motor based on the current value of the current. The method measures the motor speed and current through motor measurement and control model, generates more accurate reference currents, and achieves precise control of the motor.
