Optimal tuning of DC motor via simulated annealing

Despite the popularity, the tuning of PID controller is a difficult task to attain by researchers and plant operators. Several conventional methods had been proposed to optimize the PID controller, yet, the results were highly unsatisfactory in terms of large overshoot and big surge, thus came the requirement for more convergent algorithm and therefore modern heuristic approach such as Simulated Annealing is employed to improve the capability of traditional techniques. In this paper, a simulated annealing PID controller is designed using IAE, ISE, ITAE, ITSE and MSE error criteria for stable linear time invariant continuous system. The gain parameters Kp Ki and Kd are tuned and applied to PID controller. A comparison of system performance is observed for Ziegler-Nicholas PID and SA-PID.
