This paper presents the application of a fuzzy logic controller to improve the stability of electric power system. The stabilizing signal is computed using the standard fuzzy membership function depending on the speed acceleration state of the generator in the phase plane. Studies have been carried out considering FLPSS based on 3, 5 and 7 MFs of Gaussian shape. Investigations reveal that the performance of the proposed FLPSS is quite robust to wide variations in loading condition both for small and large perturbations. The performance of the fuzzy PSS is compared with the conventional power system stabilizer (CPSS). The simulations were tested under different operating conditions and change in reference voltage also tested with different membership functions.
