Abstract :—To supply power demands reliably, power system should cope with various disturbances and faults and its stability should be retained. A power system may be failed due insufficient damping of synchronizing torque. In this paper, to improve the dynamic stability of a power system a feedback control based on H2 method is designed. To formulate the problem appropriately, linear matrix inequality insert ignore into journalissuearticles values(LMI); theory is employed. To optimize the overall closed-loop system response, the parameters of controller is optimized using particle swarm optimization insert ignore into journalissuearticles values(PSO); algorithm. Simulation results represent the effectiveness and validity of the proposed controller and its superiority over conventional power system stabilizer insert ignore into journalissuearticles values(PSS);
