The authors describe an autotuning method for an intelligent PID (proportional-integral-derivative) control system. This method is based on the settling time of the process and is applied to the autotuning PID controller by using fuzzy logic. The autotuning algorithm proposed can tune the PID parameters online using the response characteristics of the PID control system. The performance of the controller was verified by computer simulation. Simulation shows good results. The proposed controller was tuned automatically to the optimal PID parameters under various initial conditions.>
