Improved Energy-Based Hysteresis Model and Parameter Identification for Magnetic Hysteresis Materials

This paper aims first to clarify the transition between the thermodynamic balance
from the mesoscale, at the scale of one cell, to the macroscale, at the homogenized
level. Actually this homogenization can be tackled in different ways, leading to
different construction of EB hysteresis loops, one approach being in better agreement
with experimental data. Then, the observed asymmetry between ascending
and descending branches in measured hysteresis loops, which cannot be accounted
for by the original EB model, is further investigated. An extension of the EB model
is proposed and a comparison with classical Jiles-Atherton results to material measurements
will be shown. Additionally, the parameter identification technique will
be adapted accordingly in the full paper.
