This paper proposes a new PID parameter tuning method using Chaotic Particle Swarm Optimization (CPSO) with ICMIC. The method is implemented into the PID tuning of the position control system, where the transfer function represents a plant model of a servo system. The PID parameter is computed by CPSO-based, PSO-based and ZN-based PID tuning method according to the obtained model, respectively. The simulation results show the effectiveness of the proposed tuning method, and are compared with the classical PSO and Ziegler-Nichols.
