An analytical formula to identify the parameters of the energy-based hysteresis model

Abstract

Energy-based models (also called Vector Play models) are a class of phenomenological models of magnetic hysteresis. In this work an original identification method is presented. The main advantage of this method is its speed and its robustness. Conversely to optimization-based methods, which are prone to convergence problems, the new method is based on analytical formulas. The method is tested experimentally with three different materials (a ferrite and two non oriented steels), and provide an accuracy comparable to classical identification methods, with a much lower computational cost.
