Design of Fuzzy Logic Controller Using Software Matlab/Simulink

Abstract

This paper describes the implementation of control system using fuzzy logic technology for controlled induction motor drives.  The performance of an induction motor driven by a fuzzy logic controller using a commercially available software package Simulink from Matlab.

The induction motors are generally used in the industries, because they are more rugged and reliable than the dc motor.  In the operating of motor induction, the speed is varied (not constant) when a change of parameter and load torque happens. In a conventional way, induction motor is controlled using PID (proportional integral derivative) controller. PID controller has difficulty in dealing with dynamic speed tracking, parameter variations, and load disturbances.  In this paper, control system of induction motor speed is applied using Fuzzy Logic Control. 

The simulation results to shown that the overshoot and setling-time of the set point are relative small with the fuzzy logic controller.
