PSO based controller design for a first order process with time delay

Abstract: This Paper deals with the tuning of PID controller using conventional methods and computational technique like Part icle Swarm Optimizat ion. 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 cr iteria used for comparison include time domain specifications, Performance index, robustness of the system, servo and regulatory responses.
