On the parameter identification and application of the Jiles-Atherton hysteresis model for numerical modelling of measured characteristics

Abstract

The application of the Jiles-Atherton hysteresis model for numerical modelling of measured magnetic hysteresis characteristics of constructional steel is investigated. Parameter identification is done using the stochastic optimization method "simulated annealing". Modifications of the original model, which were proposed to overcome its drawbacks, are examined, resulting in a new combined Jiles-Atherton and scaling model.
