摘要
交流电动机的数学模型比较复杂，动态特性的分析难以理解。空间向量动态结构图能比较直观地表示电机内各变量相互作用的途径，和观察坐标旋转角速度的影响。本文利用空间向量动态结构图分析了交流异步电动机转子磁场定向和定子磁场定向控制的解耦性质。
Nonlinear and cross-coupling characteristics of AC machine make the mathematical modelling rather complex.The space vector signal flow graph of AC machine dynamics depicts the reaction between state variables and the impact of rotating frame on the system equations.By visual inspection,the decoupling of AC motor drives with rotor field orientation and direct stator flux orientation control are presented.
