The second half of the book bridges the gap between the machine model and the power electronics that drive it.

The Park transformation can be represented as: $$ \beginbmatrix v_d \ v_q \endbmatrix = \beginbmatrix \cos(\theta) & \sin(\theta) \ -\sin(\theta) & \cos(\theta) \endbmatrix \beginbmatrix v_a \ v_b \endbmatrix $$ where $\theta$ is the angle between the dq-axes and the abc-axes. “They taught this in the monographs,” she muttered,
“They taught this in the monographs,” she muttered, flipping through her dog-eared copy of Electrical Machines and Drives: A Space Vector Theory Approach . The book was old—a dense brick from the Oxford Monographs in Electrical and Electronic Engineering series. Its pages were filled with Clarke and Park transforms, dq-axis models, and the elegant geometry of rotating magnetomotive forces. “They taught this in the monographs
