摘　　要：三相交流电动机具有非线性、强耦合、多变量的性质,要进行高精度控制,必须进行坐标变换。根据磁动势不变的原则,推导了三相交流电机静止三相转换静止两相、静止两相转换旋转两相的电流变换公式。应用Simulink软件对两种变换进行建模,给出了仿真参数设定的方法,分析了仿真结果,充分证明了坐标变换的正确性。坐标变换的建模与仿真能够直观地理解坐标变换的过程,坐标变换能够为矢量控制等技术打下较好的基础。Three-phase AC motor has the characteristics of nonlinearity, strong coupling and multivariability. Coordinate transformation must be carried out for high-precision control. According to the principle of magnetomotive force invariance, derived were the current transformation formulas of static three-phase transformation static two-phase and static two-phase transformation rotary two phase. The Simulink software was used to model two kinds of transformation with the method of the simulation parameters setting given, the simulation results analyzed and the correctness of the coordinate transformation fully proved. The process of coordinate transformation can be understood intuitively by using coordinate transformation modeling and simulation. Coordinate transformation can lay a good foundation for vector control and other control technologies.
