Abstract

The development of high performance variable speed brushless dc motor drive is very important in all industrial applications. Generally, a high performance BLDC motor drive system must have good dynamic speed response, reference speed command tracking capability and load regulating response. Conventional controller such as PI, PID does not provide good dynamic response due to the problem of non-linearity, difficulty in the tuning of controller parameters. With the fast growing of intelligent controllers for precise motor speed control, fuzzy logic controllers are taken in this paper. This paper demonstrates a comparative study of PI, fuzzy logic, hybrid fuzzy PID controllers using MATLAB/SIMULINK environment.
