Speed Control of DC Motor Using Interval Type-2 Fuzzy Logic Controller

Abstract

Direct current (DC) motors are considerably utilized in many implementations requiring speed and position controls. The simplicity of DC motor speed control is also the main reason for its widespread use. Recently, with rapid developments in power electronics, microprocessors and semiconductor materials, many control structures are designed for DC motors. In this study, the speed control of the DC motor is carried out using Matlab/Simulink package program. Type-2 Fuzzy Logic controller (T2FLC) that has efficient performance in modelling uncertainties is proposed for DC motor speed control. The classical Proportional+Integral (PI) controller and T2FLC are connected to the speed control unit of DC motor. Simulation studies have also been realized under several operating conditions such as tracking reference speeds and load changes. According to the obtained simulation results, it has been observed that T2FLC has better results than the classical PI controller in operating conditions.
