Modelling of unit differential reversal curves in the G2E hysteresis modelRahmanović, Ermin (Avtor) Petrun, Martin (Avtor) static hysteresis modeliron lossloss surface modelmagnetic materialmathematical modellingIron losses represent a crucial factor in the design process of electrical machines. For this reason, it is important to consider adequate hysteresis behavior within models which predict iron losses. A promising hysteresis description is the static hysteresis model developed by the G2Elab research group. It proposes a unique approach of modelling magnetization curves inside the major loop based on the so-called unit differential reversal curves (uDRCs). This work focuses on modelling of the uDRCs. We analyzed the accuracy and identification approaches of several uDRC models, where we compared the established model with simplified solutions with less parameters. Further, we analyzed the impact of individual models regarding identification convergence. Finally, we highlighted which simplified models give the best trade-off between the ease and stability of identification process of parameters, and the accuracy of the hysteresis model.Elsevier20242024-01-26 08:48:59Neznano86895sl© 2024 The Author
