| ABSTRACT Many types of drives used in positioning systems need high performance controllers to achieve good dynamic performance in the presence of system uncertainty and complex environment. Traditional control schemes like PID can not meet these requirements. On the other hand, a conventional fuzzy logic controller can usually control a nonlinear system more efficiently, and provide better performance than PID controllers in terms of shorter rise time and smaller over shot. Unfortunately, the traditional fuzzy logic controller cannot improve the steady state performance for time varying systems. To overcome this drawback, the integral of the error of the system is taken in consideration. This paper presents a hybrid of the conventional PI compensator with fuzzy logic controller to improve steady–state and dynamic accuracy of the servo position control system. The results obtained indicate that the proposed controller has an excellent position tracking performance compared with both traditional PID controller and fuzzy PD controller. | ||||
