Wind energy plays vital role in present day power generation as wind turbine system actively participate in frequency and voltage stability .Maximum power is extracted from wind turbines if some of the considerations are taken in to account such as wind speed and pitch angle. Howeverwind speed is unpredictable and depends on the geographical conditions of the different areas, pitch angle plays a vital role in extracting maximum power from the wind energy .As energy extracted is limited according to Betz Law it is evident that with the help of pitch angle controllers it is possible to get desired output for certain conditions with in such limit. Hence it is necessary to design good pitch angle controller in order to obtain maximum performance. A system with wind turbine generator is modelled and different parameters of such system is observed for different conditions and an isolatedplant system is taken for study andconventional PID controller, Fuzzy logic controller, Adaptive Fuzzy logic controller are designed and compared plant without controller. Adaptive Fuzzy controller gives the desired output with good time response characteristics with step input.
