摘要
在分析定子磁链定向的双馈电机控制的基础上,将矢量控制技术和内模控制器结合起来应用于定子电压并网控制中,得到了一种新型的并网控制方法。该控制方法并不需要建立精确的感应电机模型,动态响应快,无超调,控制器结构简单,参数单一,工程上易于实现。利用Matlab进行的仿真结果表明,该方法具有优良的动态性能。
Based on the stator flux linkage oriented control theory of doubly fed induction generator（DFIG）, the field-oriented vector control technique and the internal model controller（IMC） were combined and transplanted into the voltage control of DFIG and a novel cutting-in .control strategy was obtained. The strategy does not need the exact DFIG model, and has perfect performance without overshoot. The structure of the controller is simple, and the single adjustable parameter is directly related to system performance, so the strategy is prone to be realized. Finally ,the strategy was studied by simulation using Matlab, the result of the simulation showed that the control strategy has perfect dynamic performance.
