Fuzzy PID Controller For Pitch Angle of Wind Turbines

模糊PID控制应用于风力发电机的桨距角控制,其中风力发电机采用具有强非线性的数学模型,模糊PID控制器使用二维线性规则库和高斯型隶属度函数的结构。在MATLAB平台上搭建仿真模型,仿真结果表明采用模糊PID控制比纯PID控制效果稳定,鲁棒性强,能够有效改善风力发电系统变桨距控制效果。

Fuzzy PID is applied into the pitch angle of the wind turbine with nonlinear mathematical model,fuzzy PID controler use two dimensional linear rule library and gaussian membership functions of the structure.Setting up simulation model in matlab,The simulation results show that the effect of fuzzy PID control is better than PID control.The Fuzzy PID control has strong robustness,and is able to effectively improve wind power systems control effect.
