摘要随着石油资源的日渐枯竭以及人类对全球环境恶化的愈加关注，风能作为可再生的绿色能源逐渐成为全球普遍关注的焦点。风能开发的重要性已无可争辩，风力发电技术也随之得到迅猛发展。当前世界上主流的风力机型是变桨矩控制的大型并网式风力发电机。我国风电机组正由定桨矩型向变桨矩型过渡，因此对风力发电机的变桨矩控制的研究是相当必要的。64498
本文首先对变桨矩风机的结构组成(风力场子系统、空气动力子系统、动力传输子系统、发电机子系统等)，及其运行原理进行了研究，并在此基础上建立变桨矩风力机的数学模型。在这篇论文中一种新型的多输入多输出的风力发电机组系统递归控制理论被提了出来 ,它是以混合动力系统的分段连续系统理论作为基础的。由此开发出来的递归模型自由控制器(RMFC)拥有非常简单的结构,并且很容易地实现。最后基于simulink进行系统模拟仿真。

Title The Control and Research of Variable pitch of Wind Turbine
Abstract
With the increasing depletion of oil resources and the increasingly deteriorating human increasingly concerned about the global environment, wind energy as a renewable green energy has become the focus of widespread concern worldwide. The importance of wind energy development is indisputable that wind power technology also will be rapid development. Currently the world's mainstream wind pitch control model is large and intensive wind turbines. China's wind turbine is being used by fixed-blade variable pitch rectangular-type transition, so the wind turbine pitch control study is quite necessary.
This article first research variable pitch wind turbines structures (wind farm subsystems,aerodynamics subsystem, power transmission subsystem, generator subsystem),and its operating principle, and on this basis establish the mathematical model of variable pitch wind turbine. In this paper a new type of recursive control for multi-input multi-output wind turbine systems is proposed, which is based on the theory of a particular class of hybrid systems called piecewise continuous systems. The developed recursive model free controller (RMFC) has a very simple structure and can be easily implemented.
