A POSSIBLE ALTERNATIVE TO PREISACHS MODEL OF STATIC HYSTERESIS

A phenomenological model which represents a possible alternative to th e well-known Preisach's model of magnetic hysteresis is here presented . The main feature of the proposed model, which differentiates it from Preisach's one, is that the individual elementary <<particles>> are n ot themselves hysteretic; it is the mechanism by which the state of th ese particles is modified that introduces hysteretic behaviour. The mo del appears to be computationally less cumbersome than Preisach's one, while having the same application range.
