Comparison of Fuzzy-PID and PID Controller for Speed Control of DC Motor using LabVIEW

Abstract

DC Motors are widely used in industries because they provide better quality with high torque and low volume. A individual PID Controller and A Fuzzy Based PID Controller is proposed to design in this paper. By a comparison between both the Controllers an overview of performance of both the Controllers is provided. By the literature review it is found that many of the researchers used fuzzy controller with some algorithms to tune the parameters of the PID Controller so here for the tuning of the PID parameters Fuzzy Controller itself used. In Conventional PID Controller there is a difficulty to control the value of the parameters and get good suitable characteristic. In the Fuzzy-Controller to satisfy the control characteristics of the parameters there is special ability and that is to provide an easy computing, to control for Motor. By comparing the responses for both the controllers, Fuzzy based PID Controller presents better performance than PID Controller. To Model the DC Motor and for the simulation purpose LabVIEW software has been used.
