双馈电机的一种矢量控制实现方法

Vector Field-oriented Control for Doubly-fed Motor

由交-交变频器和基于TI公司DSP芯片的控制器构成了一种双馈调速的矢量控制系统,以矢量运算实现转矩和励磁的分解独立控制,使交流电机获得与直流电机媲美的调速性能。介绍了系统的实现方法,分析了其电路结构组成和实现原理。

In this paper, a kind of vector field-oriented controlling method, which is used for doubly-fed speed regulation, is introduced. The doubly-fed speed regulation system consists of an AC/AC cycloconverter and a DSP-based controller. By using field-oriented controlling method, the torque and the excitation can be controlled separately, and therefore the speed regulation of an AC motor is to be compared with a DC motor. Circuitry of the system and its realization method is analyzed.
