Numerical Estimation of Iron Loss with Dual models for Electromagnetic Devices

Abstract

In this work, in order to get adaptive Jiles–Atherton (JA) model parameters, an algorithm is proposed and assumes JA parameters to be the functions of magnetic field intensity H, or magnetic flux density B. These parameters are considered by using response surface model (RSM) which is based on the moving least squares (MLS) approximation. The RSMs of the JA model parameters are built based on the simulation results of Preisach model. Numerical example is involved to demonstrate the improvement in the accuracy of the modified JA model. Comparison of its predictions with measurements and with traditional JA model is also shown in this paper.
