Consistency of the Duhem Model with Hysteresis

الملخص EN

The Duhem model, widely used in structural, electrical, and mechanical engineering, gives an analytical description of a smooth hysteretic behavior.

In practice, the Duhem model is mostly used within the following black-box approach: given a set of experimental input-output data, how to tune the model so that its output matches the experimental data.

It may happen that a Duhem model presents a good match with the experimental real data for a specific input but does not necessarily keep significant physical properties which are inherent to the real data, independent of the exciting input.

This paper presents a characterization of different classes of Duhem models in terms of their consistency with the hysteresis behavior.
