A comparative analysis of different types pitch angle controller is designed in this paper to achieve a steady output torque for stable wind turbine operation. The control techniques are implemented and developed to provide a uniform constant torque to the permanent magnet synchronous generator (PMSG). The wind system consists of a wind turbine, a pitch actuator and PMSG. The control strategy used are proportional-integral (PI) and fuzzy logic controller (FLC). The performance of the control strategies is investigated in terms of aerodynamic torque, generator speed and the generator power. The complete wind energy conversion system (WECS) is developed and tested using MATLAB/Simulink. The performance of the control strategies is evaluated under varying wind-speed condition. The performance of the pitch angle controllers is found satisfactory, but the strategy with fuzzy logic-based controller shows better performance as compared to PI controller.
