交流电动机矢量控制变压变频调速系统(三) 第三讲 坐标变换的原理和实现方法

The Principles and Implementation of the Reference Frames Transform

为了简化异步电动机的数学模型,必须对其进行坐标变换,从而坐标变换是矢量控制的基础。本文首先介绍了确定坐标变换矩阵的原则,在此基础上,介绍了相变换和矢量旋转变换的实现方法。

The reference frames transform is necessary to simplify the induction motors dynamic model. It is also the base of the Vector Control. The principles and implementation of the reference frame transform is detailed in the paper.
