PSO based PID controller tuning for PMDC motor

This paper presents the optimal tuning of PID controller gains based on Particle Swarm Optimization (PSO) technique. The PSO based PID controller tuning is implemented using Integral Time Squared Error (ITSE) performance index. The efficacy of proposed controller is tested with tri-loop error driven Permanent Magnet Direct Current (PMDC) motor with different transient conditions. The simulation results, generated for each transient, show that the performance of PMDC motor is enhanced for both tracking and disturbance rejection.
