Abstract
A technical field of motor control, and a motor rotation control method and device. The method includes conducting inverse Park transformation and inverse Clark transformation to control output results of a position loop, a speed loop and a current loop to obtain SVPWM signals of a present cycle; decoupling an interrupt control cycle from a PWM signal reference channel; acquiring present position sampling information of a motor, and predicting the position sampling information to obtain position result information of a motor rotor in predicted cycles. In the motor rotation control method, an interrupt function trigger signal is added to realize decoupling from the PWM signal reference channel, so that SVPWM signal update frequency of motor control will not be affected when CPU load is reduced by adding an interrupt function scheduling cycle.
