Modified Jiles―Atherton model and parameters identification using false position method

Abstract In this paper, a modified Jiles–Atherton model is proposed. This model uses a physical meaning by introducing the magnetization M instead of the irreversible magnetization Mirr in the effective magnetic field He-magnetic field H relationship. The false position method is coupled to the iterative algorithm to identify the Jiles–Atherton parameters for both classical and modified Jiles–Atherton model. These parameters are evaluated by the resolution of three nonlinear equations obtained from three conditions. The validity of the modified model is done by comparing the obtained hysteresis loops to the experimental ones.
