Calculation of Jiles-Atherton hysteresis model's parameters using mix of chaos optimization algorithm and simulated annealing algorithm

Abstract

A mix of chaos optimization method and simulated annealing method to calculate the Jiles-Atherton (JA) model's parameters is proposed in this paper. The new method costs less time in calculating the JA model's parameters. During the search performance, the local extreme value can be avoided effectively. A modified JA model is applied in this paper, choose the magnetic flux as the confident variable. The model can be directly used in time-domain finite-element calculations applied to the magnetic vector potential formulation. The curve which calculated using the obtained parameters is well agreed to the measured curve by experiment.
