Magnetic Hysteresis Impact on HF Signal Injection

This article presents a model of a Synchronous Reluctance Motor (SynRM) at standstill, including magnetic hysteresis, to study its impact on High-Frequency (HF) signal injection. So that it can easily be simulated, the model is rewritten under state-form. The parameters of the model are identified, based on experimental data, using a customized fitting procedure adapted to hysteresis curves. The proposed model explains the impact of magnetic hysteresis on HF signal injection and reproduces accurately the experiments.
