A Vector Control System of PMSM with the Assistance of Fuzzy PID Controller

In this paper, the speed loop and current loop controllers in vector control system are improved by using fuzzy control theory with parameter self-tuning function. The vector control system model of permanent magnet synchronous motor (PMSM) is established in MATLAB/Simulink environment. The speed control of PMSM under starting and sudden load is simulated. Comparing the performance of traditional PID control and fuzzy PID control, the results show that fuzzy PID control perfectly combines the accuracy of PID control with the dynamic characteristics of fuzzy control.
