Adaptação do modelo de Preisach para histereses assimétricas: aplicação ao caso VO2.

Abstract

The models for hysteresis presuppose that the hysteresis curves present some characteristics what it limits the application of these models. The use of these models t o describe hysteresis that do not has the these characteristics, it can only be done through some adaptations. This work concentrates on the study of one of these hysteresis models, the model of Preisach, and it proposes some adaptations t o the model so that he can be used in the representation of asymmetric histereses.
