Abstract

This dataset provides the numerical results and optimization routines used to harmonize different Jiles–Atherton (JA) hysteresis model variants. The goal of the study was to determine whether parameter sets of one JA formulation can be transformed such that another formulation reproduces the same B(H) behaviour.

Technical Information

This dataset contains the numerical routines and optimization results used to establish parameter mappings between different Jiles–Atherton (JA) model variants. Synthetic B(H) curves were first generated for a selected reference model over multiple magnetic-field amplitudes. These curves served as target data for a Differential Evolution (DE) optimization scheme implemented in MATLAB. For each target curve, the parameters of the alternative JA models were optimized such that their simulated B(H) trajectory matched the reference model.
