A NEW MODEL OF SCALAR MAGNETIC HYSTERESIS

In this paper the scalar quasi-static magnetic hysteresis is described by means of a new model based on a sequential algorithm, which appear s to be a possible alternative to the classical Preisach model. A proc edure leading to the identification of the model parameters is describ ed. The hysteretic behavior obtained by using the new model is in good agreement with experimental measurements as well as with the predicti ons of the Preisach model. Finally, both models have been applied to s tudy the dynamics of a circuit with an hysteretic inductor, driven by a sinusoidal voltage source. Good agreement between the two simulation s was found, but our model appears computationally less cumbersome tha n that of Preisach.
