Robust tuning of embedded intelligent PID controller for induction motor using bacterial foraging based optimization

Abstract

In this paper, design approach of PID controller with rejection function against external disturbance in motor control system is proposed using bacterial foraging based optimal algorithm. To design disturbance rejection tuning, disturbance rejection conditions based on H∞ are illustrated and the performance of response based on the bacterial foraging is computed for the designed PID controller as ITSE (Integral of time weighted squared error). Hence, parameters of PID controller are selected by bacterial foraging based optimal algorithm to obtain the required response. © Springer-Verlag Berlin Heidelberg 2005.
