    根据当前世界能源的形势,风力发电作为新能源中技术最成熟、最具规模开发条件和商业化发展前景的发电方式之一,已成为各国学者竞相研究的热点。双馈风力发电机具有变频器功率小、功率因数高、动态性能稳定等优点,而且非常适用于中小容量伺服领域和高精度、高动态响应伺服场合。因此,双馈风力发电机是目前风力发电采用最广泛的机组类型。但由于双馈风力发电机又具有严重的非线性、强耦合、参数时变等特性,而且电机中的调节器大多采用PI控制为主。当工况参数发生较大变化时,常规的PI控制器很难获得满意的控制效果。因此,为了提高双馈风力发电机的动态性能,解决双馈风力发电机非线性、参数时变等问题,必须寻找到先进的参数辨识控制策略。...According to the current situation of the world energy, wind power, one of the power generating ways with the most mature technology, the largest commercial development conditions and development prospect, has become a hot research area to scholars of all countries. Doubly-fed wind turbine has the advantages of low frequency converter, high power factor and stable dynamic performance, and is suita...学位:工学硕士院系专业:信息科学与技术学院自动化系_系统工程学号:2322009115291
