Generalized DQ model of the permanent magnet synchronous motor based on extended park transformation

A generalized dq model of the permanent magnet synchronous motor (PMSM) based on newly defined extended Park transformation is presented. The new model can describes all kinds of editions of the PMSM dq model together, such as the edition based on Park transformation, the edition based on the principle of power invariance, and so on, for which it can avoid confusion and prevent misusing of different editions at root. The model equations derivation is shown step by step and model compatibility is also verified. The simulation of the vector controlled PMSM drive based on the new model, which is instantiated to some edition, is performed to investigate the performance of the drive in Matlab. The simulation results confirm the new model´s compatibility further.
