| 摘 要： | 在分析额定风速以上风力发电系统变桨距控制研究现状和风轮机模型开环控制性能薄弱的基础上,阐明了桨距角控制的必要性和优越性。采用状态反馈线性化理论对风轮机模型进行精确反馈线性化处理,得出其全局线性化模型,并用最优控制进行桨距角控制。在MATLAB环境下进行仿真,得出结果,并进行分析比较。

| Abstract: | The necessity and advantage of active angle control were expounded based on the analysis of the active angle control at wind velocity higher in wind electric power system and the weak open-loop performance of turbine model.The theory of state feedback linearization was adopted to create its accurate linearized model controlled with the optimal control method.The model was simulated under MATLAB,and the wave shapes were analysed with comparison. |
