In this paper, the authors deal with the tuning of PID controller using conventional methods and computational technique like particle swarm optimization. The main objective is to prove that the response obtained is more stable, robust and efficient when PID is tuned using PSO. The obtained value is compared with conventional methods like Ziegler Nicholas, Cohen-coon and internal model control. The criteria used for comparison include time domain specifications, performance index, and robustness of the system, servo and regulatory responses.
