Fuzzy logic and neural network control strategies are studied. Based on the servo system of PMSM, fuzzy logic and RBF neural network are used to tune the PID controller’s parameters, and put forward a kind of auxiliary scheme about RBF neural network tuning PID controller. The simulation results show that, for difficult to establish the precise mathematical model of the time-varying, nonlinear systems and linear controller and traditional PID controller cannot obtain satisfactory control effect, combining fuzzy logic and neural network with the conventional PID can make the servo system has strong robustness, preferable control precision and faster dynamic response.
