Abstract
This paper presents a comparative study between the performance of Model Predictive Control (MPC) and optimal PID controllers in terms of various performance measures. Parameters of the PID controller are adjusted based on Bacterial Foraging Optimization (BFO) algorithm and its results are compared with those obtained using MPC controller in terms of some control parameters. These control parameters are rise time, settling time, peak overshoot percentage, integral of absolute errors and integral of time multiplied absolute of error for both MPC and PID controllers. Many case studies are considered in this article. First, second, third, fourth and fifth order systems are investigated. Simulation results indicate that MPC controller outperforms optimal PID controller in all cases.
