Résumé :

In this work we present the Preisach model for the simulation of the magnetic hysteresis. This model is able to represent the hysteresis property of versus materials if it’s distribution function µ(α,β) and his parameters are well determined. Four distributions functions, the modified Lorentzian, Guassian, Gauss-Gauss and lognormal- Gauss are used and optimized to simulate the hysteresis loops. In the last step, the optimal distribution function and there parameters of the Preisach model are determinate via practical swarm optimization (PSO) and results are compared with experimental ones.
