摘　　要：设计出独立桨叶控制系统的机构方案,依据空气动力学分析,提出模糊控制结合以桨叶空间方位角作为主体因素的加权系数的控制策略,建立了系统模型,仿真结果表明,在风速高于额定风速时,作用在桨叶上的负载波动大为减小,输出功率维持在额定功率附近。Wind turbine individual blade control system adjusts the pitch angle of each blade separately to reduce the torque fluctuation of the blade caused by the spatial variation of wind speed, and to steady the output power. The design of the individual blade control system framework was presented. Based on the research of wind turbine aerodynamic characteristics, the system model was built. The control strategy is to combine fuzzy control with the weight number that was mainly decided by the blade azimuth angle. The simulation result indicated that when the wind speed was above rated, the pitch load fluctuation was greatly reduced and the output power was kept around rated.
