Based on Brushless DC Motor of Fuzzy and PID Control System

Abstract

The brushless DC motor (BLDCM) is a multi-variable and non-linear system. PID control and Fuzzy control have been used in the field of the BLDCM control. However, the design of the reference model is fix with structure, the tradition PID doesn't have from whole settle with artificial with experience modification PID parameter, PID control of the fuzzy controller are not satisfied. In this paper, PID fuzzy control system based on is presented so the controller is applied into the BLDCM control. In Matlab/Simulink, the simulation result showed that the correction by using fuzzy controller, to BLDCM system for real-time control, system stability improvement at the same time, response speed, feed system and raises the comprehensive performance. The validity of the model was verified and thus a new way was provided for further research of the motor.
