交流电机动态分析中坐标变换的归一化方程

交流电机的动态分析和运动控制中,需要根据不同的情况采用不同的坐标变换来分析问题,因此坐标变换对交流电机的动态分析具有重要的意义.由于每种坐标变换的变换矩阵系数、形式不同,为了获得电机常用坐标变换的归一化形式,依据综合矢量理论基础,研究四种坐标系与自然坐标系的关系和变化规律,给出了交流电机动态分析中坐标变换的归一化方程,便于程序化和模块化,为交流电机的动态分析和运动控制等问题的研究提供了理论依据.

Uniform Formula of Reference-frame Transformation under Dynamic Analysis of AC Motor

In the dynamic analysis and motion control of AC motor,specific problems are analyzed by various reference-frame transformations meant to the research of dynamic process according different situations.To obtain the uniform forms of reference-frame transformations in view of the difference of coefficient and form about transformation matrix,the relationship and change regulation between these four reference-frame and natural coordinate is discussed and the uniform formula of reference-frame transformations is deducted based on the fundamental concept of synthetic vectors for convenience to program and modularize.The theory evidence for the researching problems about dynamic analysis and motion control of ac motor is provided.
