坐标变换系数的选取及对电机控制算法的影响

摘要

Coordinate transformation is an important tool in motor vector control method. However, meaning of the coefficient in front of the transformation matrix hasn’ t been explained clearly in many previous works, which causes confusion easily. Motor models under different coefficient condition are derived;influence of the coefficient on reference variables in vector control methods is concluded in a systematic way.%交流电机的矢量控制需要坐标变换，但现有文献中对其中的3/2变换矩阵前系数缺乏清晰的说明，在应用中易引起混淆。详细推导了不同系数情况下的电机模型及矢量控制算法中参考量和该系数的关系，并进行了系统的理论归纳。
