With the rapid development of the economy and power electronics, permanent magnet synchronous motor (PMSM) is widely used in various fields, vigorously promoting the development of China’s equipment manufacturing industry in the era, and the related topics have become a hot topic nowadays. However, permanent magnet synchronous motor control systems are characterized by non-linearity and time-varying parameters, which pose a threat to the reliability of practical engineering applications. Based on this, this paper combines an improved grey wolf optimization (GWO) algorithm with a PID controller to establish a general model of a permanent magnet synchronous motor speed control system, including control, drive and feedback modules, to achieve accurate control of the running speed of a permanent magnet synchronous motor. Finally, the simulation model of space vector pulse width modulation (SVPWM) based system is built by MATLAB/SIMULINK, and the simulation and analysis of corresponding parameters are completed given a definite input signal.
