Identification procedures for scalar Preisach model

To represent a ferromagnetic material with the scalar Preisach model the Preisach distribution or the Everett function must be known. In this paper different identification procedures of the scalar Preisach model are summarized. The Everett function is determined in two different ways, from first-order reversal curves and from concentric hysteresis loops. Solving a bilinear system of equations the Preisach distribution is computed pointwise from the major hysteresis loop. In several cases it is convenient to approximate the Preisach distribution analytically. As a novelty of the paper a distribution function for which the Everett function can be expressed in closed form is presented.
