Hysteresis, defined as a rate independent memory

effect, is a phenomenon that occurs in many

physical systems. The effect is sometimes

desired, sometimes a nuisance, sometimes cata-

strophic, but in every case we must understand

hysteresis if we are to better understand the

system itself.

This work introduces a method of parameter

identification for the Preisach model of hyster-

esis. This identification method is explored

in both the setting of non-singular measures

and the setting of singular measures.
