摘要:
针对风能转换系统(WECS)强非线性﹑参数不确定性的问题,设计基于模糊性能估计器的T-S模糊状态反馈控制器。以高速杆转速和电磁转矩为前提变量,采用无损调试方法,利用隶属度函数构建了整个全局模型模糊状态反馈控制器。实现了WECS模型的模糊动态化,减小了建模误差和外界扰动影响。仿真结果表明:该控制器能将风能转换系数和叶尖速比控制在最优值附近,实现了额定风速下风能捕获的最大化。
Abstract:
In view of the problems of nonlinearity of wind energy conversion system(WECS)and uncertainty of parameters,a TS fuzzy state feedback controller is established based on a fuzzy performance evaluator.The highspeed shaft rotational speed and electromagnetic torque are used as premise variables.A nondestructive testing method is applied.The fuzzy state feedback controller of globe models is established using membership functions.The fuzzy dynamic model of wind energy conversion systems is realized,and the modeling errors and disturbances are decreased.Simulation results demonstrate that with the proposed controller,the wind energy capture ratio and the tip speed ratio can be maintained around the optimal values,and the maximization of wind energy capture ratio under the rated wind velocity is realized.
