Hysteresis modeling

In the modeling of transducers, especially magnetic transducers, hysteresis may affect performance. Hysteresis models have been improved greatly and a re capable of modeling a large variety of rate-independent phenomena, and a re capable of describing minor loops. Of these, the most useful are: the Pr eisach model, the play model, and the stop model. Coupling these purely mag netic models with other phenomena, such as magnetostriction, enhances the m odel's usefulness for transducer applications. This paper will discuss the conditions under which these models may be inverted, and for the invertible media, a technique fur inverting them.
