4.1.3 Park Transformation

Park transformation, transforms quantities from stationary reference frame to rotating reference frame. As the rotor rotates, the rotor flux rotates in space and it is the position of the flux vector that is taken as reference for transformation. The park transformation is expressed by the following equations.

Where, ө is rotor flux angular position, as shown in the following figure.
