| The paper evaluates different variants of the Jiles-Atherton model of magnetic hysteresis, focusing on the experimental verification of the model's hysteretic component characteristics. Five modelling strategies were examined: the original Jiles-Atherton model, a modified variant proposed by Venkataraman et al., the approach of Cheng and coauthors, as well as the modification proposed by Pytlík et al. Grain-oriented electrical steel was selected as a benchmark due to the complex shape of both its anhysteretic magnetization and hysteresis loop. Quantitative evaluation of the obtained results enables the assessment of the quality of hysteresis behaviour reproduction in anisotropic electric steel. Moreover, it enables verification of the functional properties of different modelling approaches used for inductive components in electric devices. |
