Abstract: In todays fast growing world, there is an urgent need to increase the production rate in process industries which consists of numerous non-linear processes. Hence it is important to design a stabilizing controller. The aim of the paper is to design optimum Proportional- Integral- Derivative (PID) controller using Particle Swarm Optimization (PSO). In this paper the algorithm is applied to control the position head of the hard disk controllers using both PID and PSO-PID controllers. The performance of PID controller is compared with PSO-PID controller by calculating Overshoot value, Rise time, Settling time and Steady state error in both the cases. According to simulation and experimental results PSO-PID controller is proven to be more efficient and result also suggests that PSO converges with less number of functional evaluations.
