摘要
无刷双馈电机(BDFM)调速系统可以大大降低调速装置的容量,在大功率调速系统中有着广阔的应用前景,但由于缺乏有效的控制策略,阻碍了其应用和推广,因此迫切需要新型的控制策略来改善其性能,以扩大其应用范围。在同步参考系的矢量解耦数学模型基础上,利用同步角和转矩的关系,提出了一种简单实用的矢量解耦控制,采用这种控制方法,使BDFM的矢量控制变得与普通感应电机的矢量控制一样简单,能用于调速性能要求较高的调速系统。
Brushless doubly-fed machines （BDFM） show potential benefits in adjustable speed drive systems of large power by their reduced converter size. Up to now, there is not a good control strategy for BDFM, which limits the application of BDFM. In order to improve performance and extend application, there must have some new control strategies. Taken advantage of the relation between synchronous angle and torque, a simple and practical vector decoupled control strategies is proposed in this paper. Moreover, this control method is simple, and its complexity is comparable to vector controllers for conventional induction machines. Therefore, this control method is appropriate for high performance drive systems.
