Design Of PID Controller In Automatic Voltage Regulator (AVR) System Using PSO Technique

In this paper, an evolutionary computing approach for determining the optimal values of the proportional-integral-derivative (PID) controller has been proposed. Proper tuning of such controllers is obviously a prime priority as any other alternative situation will require a high degree of industrial expertise. This paper demonstrated in detail how to employ the PSO method to search efficiently the optimal PID controller parameters of an AVR system. The proposed algorithm has been applied in the PID controller design for the AVR system. A MATLAB simulation has been performed and a comparative study between the proposed algorithms with the PID Controller Tuner has been studied in the presented work. In continuation of this, the proposed method was indeed more efficient and robust in improving the step response of an AVR system.
