Fuzzy logic based pitch angle controller for variable speed wind turbine

This paper proposes a Fuzzy Logic based controller for implementing Active Pitch Angle Controller in horizontal axes wind turbine. A new improved model of wind turbine is presented. By using fuzzy logic based pitch angle controller, output power of wind turbine is regulated during extremely high wind speed. Based on its inputs, the controller has fast response which can decrease mechanical fatigues in wind turbine components. The proposed controller model has been successfully validated on Matlab/Simulink software.
