Traditional power system stabilizers rely on linear design methods. In the present paper, a novel approach for design of PSS using Fuzzy C Means is presented. The proposed Fuzzy C Means PSS (FCMPSS) is trained with the pre-designed two input PID fuzzy logic PSS(FLPSS). The simulation results of the proposed FCMPSS are compared to those of conventional stabilizers and the pre-designed Fuzzy PSS for a Single Machine Infinite Bus (SMIB) system. The effect of system parameter variations on the proposed stabilizer performance is also examined. The results show the Robustness of the proposed FCMPSS and its ability to enhance system damping over a wide range of operating conditions and system parameter variations.
