Abstract. The paper proposes a control method called fuzzy logic based reference (set-point) control. The proposed control method is designed to reduce inherent limitation in the conventional feedback control systems resulted from high gain feedback selection in order to achieve fast transient response. The reference control method improves the transient response performance without affecting dynamic behaviour of the conventional closed loop system. In this paper, the PID controller is selected as the feedback control system and the reference control is implemented by using fuzzy logic decision based on the error signal of the feedback control. Performances of the proposed fuzzy logic based reference control combined with the PID controller method are shown by several simulation results on first and second order systems.

Keywords: Fuzzy Logic; Hybrid Control Systems; PID Controller; Transient Response.
