Hybrid Fuzzy Logic controller, Pitch angle, Permanent Magnet Synchronous Generator, Wind TurbineAbstract
The Pitch angle control is the best practice to regulate the aerodynamic torque of the wind turbine at high wind speeds. The mathematical model of the wind turbine system is required for the conventional pitch angle control which usually uses Proportional Integral(PI) and Proportional-Integral-Derivative(PID) controller. In this paper a novel Hybrid Fuzzy Logic controller is designed to control Pitch angle, it doesn't require much knowledge of system model. Taking generator output power error and turbine speed as inputs the FLC produces Pitch angle reference, will compensate non-linear sensitivity of the wind turbine. The proposed method is carried out on a 2MW Permanent Magnet Synchronous generator (PMSG) wind turbine system at wind speeds of 12m/s and 14m/s in MATLAB/Simulink.
