Title: Fuzzy Individual Pitch Control Based on Distribution of Azimuth Angle Weight Coefficient
Abstract: A control method is proposed to the imbalance of blade stresses in collective pitch control system of megawatt scale wind turbine. First, the three collective pitch angles can be calculated by fuzzy control algorithm. Then distribute the three pitch angle through weight coefficient of rotor azimuth angle. And the respective pitch angle of the three blades is obtained. The blade stresses and power output are simulated and verified by SIMULINK. Result shows that the method not only can steadies output power of generator but also reduce blade stresses of rotor.
