- Abstract
Time delay is a challenging problem that is frequently encountered in many fields of engineering systems. In this paper, an optimal proportional integral minus proportional derivative (PI-PD) controller with a modified smith predictor (MSP) for varying time delay systems is proposed. The optimal value of the tuning parameter sets of the PI-PD controller for step reference tracking and disturbance rejection is obtained based on two swarm intelligence techniques named flower pollination algorithm (FPA) and heap-based optimization (HBO). Three-time delay processes are used for evaluation. To evaluate the performance of each control structure, a compromised cost function between minimizing the control effort and improving the time response of the system is used. The simulation results based on MATLAB show the PI-PD controller with MSP tuned by HBO exhibits better performance than other controller structures.
