Control Design of Generator Power Systems is important to stabilize the electricity supply. The single machine infinite bus is one of generator power system models. The Power System Stabilizer (PSS) is used to damp the mechanic electro oscillation in electricity power systems. Here, the output feedback controller of single machine infinite bus is designed. The mathematical model of systems is non linear, so before designing the controller, some researchers approached it as a linear system. Here, those non linear systems are approached by applying the Takagi-Sugeno fuzzy method, with active power (P), reactive power (Q) and external reactive (Xe) as fuzzy parameters. In this paper, the performance of system without controller, with controller without fuzzy and with fuzzy controller were compared. Some types of P, Q and Xe are given to see the performance of fuzzy output feedback controller in single machine infinite bus.
