针对风力发电机组非线性、时变性的问题，提出采用模糊PID控制器作为变桨距控制器，在风速高于额定风速时，依据风速变化情况调整桨距角，从而使风电机组保持恒功率输出，最后在MATLAB平台上搭建仿真模型。结果表明，采用模糊PID控制比传统PID控制具有更好的动态性能和静态误差，能够优化变桨距控制方法。

Aiming at the problems of nonlinear, time-varying in the wind turbines, Fuzzy PID controller is established as a variable pitch controller. Pitch angle is adjusted according to wind speed to keep constant power output when the wind speed is higher than the rated wind speed.Finally,building the simulation model in the MATLAB platform.Results show,Fuzzy PID controller has better dynamic performance and static error than the traditional one. It can optimize the variable pitch control method.
