Design of Fractional Order PID controller using Soft computing methods for a Buck-Boost converter

Fractional order controller is widely used in most areas of science and engineering, being recognized its ability to yield a superior control in many dynamical systems.This work proposes the applications of a Fractional Order PID (FOPID) controller in the area of Power Electronics for a DC-DC power converter to evaluate the use of Fractional Order PID controller with soft computing techniques.To design Fractional Order PID controller is to determine the two important parameters λ (integrator order) and μ (derivative order).In this article that the response and performance of Fractional Order PID controller is compared with closed loop conventional PID controller.In all the cases the Fractional Order PID controller much better than conventional PID controller for the given system.
