Application of AIS on closed loop controller design in buck converter

Abstract

The present work details on design of closed loop controller in buck converter by using AIS (Artificial Immune System) algorithm. At present condition, the dynamic response by the conventional controller is not similar in various operating points. Hence, the work is carried out by keeping controller design as an optimum one and the parameters of controller are derived from AIS algorithm. The performance of the controller is tested under difference in load, reference voltage and input voltage.
