Abstract

The main objective of this paper is to apply the principle and technology of fuzzy logic controller (FLC) using PID controller for the speed control of brushless direct current (BLDC) permanent magnet motor drive. The controller is designed to track variations of speed references and to stabilize the output speed during load variations. The BLDC has some advantages compare to the other type of motors, because of its nonlinear drive characteristics, it is difficult to handle by using conventional PID controller. The BLDC motor is fed from the inverter where the rotor position and current controller are the inputs. Tuning parameters and its computation using conventional controller is difficult and also it does not give satisfied control characteristics. In order to overcome this here it is proposed to use FLC, it gives better control performance compared to conventional controller. The effectiveness of the proposed scheme is verified by simulating the model in MATLAB-simulink, which says that the proposed scheme gives a significant improvement in control performance compared to the conventional controller.
