Application Of Robust Engineering Approach For Dc Motor Controller Design

Abstract

This article presents the application of robust engineering to the design of a controller for DC motor application. The objective of the research is to control the speed of the DC motor using robust engineering approach. The Taguchi’s Robust Engineering approach is used to design controllers for DC motors. The initial range of the controller is identified using the Internal Model Control approach. Both, noise and control parameters, are accommodated in the experimentation. The optimal value of the Proportional-Integral-Derivative (PID) controller derived from the Taguchi Robust Engineering resulted in faster settling time. The Internal Model Control (IMC) based PID design approach and the Taguchi- based PID design approach for controllers are compared for both nominal plant models along with ±10% uncertainty in all the process parameters. The results prove the effectiveness of the robust engineering to design a DC motor controller using Taguchi method. Eventually, a regression equation is proposed based on the results of the study to facilitate academicians and researchers to delve deeper in the field.
