Research Article A New Method for Tuning PID Parameters by Using Clone Selection Algorithm

In order to improve the control performance of PID controller, a new method based on an improved clone selection algorithm (CSA) and the criteria of monotonic fitness function was introduced. Experimental results on 3 typical control systems (second order control system, high order control system, and second order control system) indicated that the proposed method could obtain optimum PID parameters and have better control performance than those methods based on GA and PSO methods,with faster response speed, shorter adjusting time and smaller or no overshoot
