Robustness Analysis with Perturbation for Control System with GWO

This paper deals with robustness and comparative analysis of GWO algorithm with different performance indices to control a system with perturbation. IAE, ISE, ITAE and ISTAE are different performance indices used in the present work for the optimization and tuning of the controller. These indices have been considered to be minimized by GWO algorithm to control the BH system. The robustness analysis has been carried out with ±5% perturbation in the location of the poles. The GWO tuned PID controller has also been applied on the perturbed systems. The comparative analysis has also been carried out for the system with perturbation in the poles.
