The study of fuzzy- PI controller of Permanent Magnet Synchronous Motor

In this paper, a new composite control strategy is proposed for Permanent Magnet Synchronous Motor(PMSM) drives to achieve fast dynamic response and minimum steady state error. Based on the prior given the scope of the deviation, it implemented the automatical switch between fuzzy control and the PI control, and designed the control system model of permanent magnet synchronous motor. It established the PMSM control simulation model, the simulation results showed that the controller had a quick dynamic response, and eliminated basic steady-state error, which has good robust, dynamic characteristics and stability.
