A Fuzzy PID Controller in the System of BLDCM

Li Fang Xu, Yong Han

Abstract

Based on the basic characteristics of fuzzy control theory and the general PID controller, a fuzzy PID controller is proposed for brushless DC motor (Brushless Direct Current Motor-BLDCM) control.The output signal PD-type is used as the input signal of fuzzy controller.Fuzzy PID controller can be adaptively adjust the PID control parameters to achieve operational control of BLDCM control system. Simulation results show that, compared with the general PID controller, fuzzy PID controller shows better characteristics on the respects of dynamic response overshoot and stability regulation time.
