On PMSM Model Fidelity and its Implementation in Simulation

Choosing the right fidelity of PMSM model for different applications help control engineers save time spent in developing system level models and testing the hardware. In this paper, three levels of PMSM model fidelity are explained from the simulation point of view and the temperature dependency is independently analyzed. Practical saturation and spatial harmonics PMSM modeling and workflows involving ANSYS Maxwell and Matlab Simulink are proposed in this paper for the fast creation of high fidelity models. The detailed workflow of creating a high fidelity reduced order model for a Permanent Magnet Synchronous Machine (PMSM) in Maxwell and the steps to import the ROM to Simulink for control algorithm development are also discussed.
