A Particle Swarm Optimization approach for PID controller system with disturbance

This paper proposes a Particle Swarm Optimizer (PSO) based PID controller combined with the low-pass filter to overcome influence of disturbance. In practical applications, the ability of interference avoidance of PID controller should be considered in evaluating the performance of system response. In this study, the PID controller can combine with the low-pass filter in order to reduce interference of disturbance and track the input signal. The simulation results show that the disturbance rejection and set point tracking are satisfied and demonstrate the performance and system stability.
