In an induction motor field orientationvector control system, the rotor time constant may be deviated due to motor temperature variation and flux saturation.
本文在异步电动机矢量控制系统中提出了一种基于转子磁场定向的转子电阻自适应辨识方法。

And, if you pay attention to the orientation conventions, you'll see that you need to take it with normal vector pointing up.
如果你注意到了方向的约定，你会发现它的法向量是向上的。

The orientation that will work for this theorem is choosing the normal vector to point outwards.
