In this paper, the Power System Stabilizer is designed using LQR and Robust H∞ loop shaping technique in order to maintain the stability of the system. The weighting function of Robust H∞ loop shaping technique is determined using Genetic Algorithm. The main objective of this paper is to achieve desired stability and analyze the robustness of the centralized controller for multi-machine system and the comparison is made between the LQR based PSS and Robust controller. The LQR based PSS is tested even under perturbations. The suitability of the proposed approach for PSS proves the robustness of the proposed design
