Design of Enhanced PID Controller Using Improved Cuckoo Search Algorithm

Abstract

One of the utmost challenge in conventional control engineering is to gratify the glitches, which are categorized by numerous objectives. In modern control system, monitoring and physically altering the operating conditions of a dynamical system has been done using an efficient controller to achieve a consistent, governable and steady system. PID (Proportional-Integral-Derivative) controllers have been used because of their strong performance enhancement applications using the basic three parameters i.e. the proportional gain, the integral gain and the derivative gain which have to be tuned for achieving an optimized control performance. In this article, an attempt has been made to design an Improved Cuckoo Search (ICS) algorithm and hence enhanced convergence performance has been noticed. In this regard, numerous benchmark functions have been considered. Moreover, amended system performance has been witnessed using Improved Cuckoo Search (ICS) algorithm by varying gain parameters of PID controller. Finally, the response of the proposed Improved Cuckoo Search (ICS) optimized PID controller has been compared with Cuckoo Search (CS) optimized PID controller and conventional PID controller.
