Simulation Research on PMSM Vector Control System Based on SVPWM

Classic SPWM control mainly focused on making the output voltage of inverter transformer as close as possible to the sine wave, did not take into account the output current waveform. The voltage space vector PWM (SVPWM) control, considering the inverter and AC motor as an integral whole, control the inverter in accordance with the circular track of the rotating magnetic field, can work better. In this paper, introduce the basic space vector PWM (SVPWM) principles, and build permanent magnet synchronous motor vector control system simulation model based on SVPWM in MATLAB/Simulink environment, and finally study the entire system simulation, by output waveform analysis, validate the system has good static and dynamic performance.
