MODELS OF MAGNETIC HYSTERESIS BASED ON PLAY AND STOP HYSTERONS

This paper deals with mathematical models of magnetic hysteresis imple mented by assembling hysterons of play and stop type. A procedure for the identification of these models is described, and their behaviors a re compared to experimental results. A comparison to the Preisach and Prandtl-Ishlinskii models is performed.:It is shown that the Play-Type Model is a possible alternative to Preisach's algorithm, whereas the Stop-Type Model is apt to represent the inverse of Preisach's operator . Simulations adopting both models are reported and compared to experi mental data, Moreover, an application to the analysis of a ferroresona nt circuit is studied, both numerically and experimentally.
