Control surface design of single-input Fuzzy PI controller for brushless DC motor drive

Abstract

The paper presents an analysis on the effect of control surface of the Single-Input Fuzzy PI Controller on the brushless DC motor performance. The analysis is carried out to determine the most suitable and appropriate control surface that could be used for the BLDC motor drive control system. The control surface of SIFPIC is mapping in one dimension using a piecewise linear approximation as the SIFPIC is simplified to sole-input variable. The analysis is done through simulation work using MATLAB/Simulink with different degrees of non-linearity of control surface. The performance of BLDC motor is observed through speed, current and torque response. From simulation result, an appropriate control surface is chosen for SIFPIC that most suit for the current system.
