The simulation study based on the space vector modulation method for PMSM control system

Depend on mathematical model of the AC Permanent Magnet Synchronous Motor (PMSM) loop control system, and space vector modulation method, we make model-analysis and simulation for positioning loop, velocity loop and current loop. Simulation results show that the current has little harmonics but fast response speed, can change fellow the load change in time, to control the speed steadily. According to the change of position, the given speed can be adjusted timely, as a result the system can position precisely.
