摘要
根据风能转换系统的状态方程,结合T-S模糊模型良好的局部线性的特点,建立了风能转换系统T-S模糊控制模型。然后针对新的风能转换系统模型设计了模糊控制器。仿真结果表明在额定风速以下,T-S模糊控制方法能够将风能转换系数控制在最优值0.476附近,叶尖速比也可以维持在最优值7附近,能够实现额定风速以下的最大风能捕获。
Combining with the state equation of wind energy conversion system（WECS） and fine part-linear characteristic of the T-S fuzzy model, a novel WECS model was proposed. A T-S fuzzy controller was designed based on the new T- S fuzzy model. The simulation resuhs demonstrate the feasibility of the proposed control method. With the T-S fuzzy con- troller,the wind energy capture ratio can be maintained around its optimal value （0. 476 ） and the tip speed ratio can be maintained around its optimal value（7） ,so it is feasible to maximize the wind energy capture below the rated wind speed,
