Abstract :
In this paper, we will discuss the use of the Lorentzian function as a possible candidate for the accurate approximation of the Preisach function in the modeling of scalar hysteresis for nonoriented grain steels. In particular we discuss here the identification procedure of the parameters of the function from measured data.
