Abstract :proportional-integral-derivate insert ignore into journalissuearticles values(PID); controller for an automatic voltage regulator insert ignore into journalissuearticles values(AVR); system using a heuristic gravitational search algorithm insert ignore into journalissuearticles values(GSA); based on mass interactions and Newton`s law of gravity. The determination of optimal controller parameters is considered an optimization problem in which different performance indexes and a performance criterion in the time domain have been used as objective functions to test the performance and effectiveness of the GSA. In the determining process of the parameters, the designed PID controller with the proposed approach is simulated under different conditions and the performance of the controller is compared with those reported in the literature. From the numerical simulation results it is clear that the GSA approach is successfully applied to reveal the performance and the feasibility of the proposed controller in the AVR system.
