The AVR without any controller does not ensure robust stability of the system. To ensure this characteristic, PID controller is used in conjunction with voltage regulator and PSO algorithm is used to tune the parameters of PID to get the better outputs. MATLAB turned out to be a useful tool and it is used for the optimization process. The paper also shows us the comparison of AVR output without controller and with PSO tuned PID controller.
