Parameter Optimization and Study of Inverse J-A Hysteresis Model

A method for parameter identification of J-A hysteresis model is presented. This method is based on combination of pattern search and nonlinear least square method. The B-H curve of different toroid and Epstein samples are obtained experimentally. The parameters of J-A model are determined by proposed parameter identification method. There is very good agreement between experimental data and predicted B-H curve for different extensive samples.
