Nonlinear Dynamics of a Hysteretic Transducer with Nonlocal Memory — •Sven Schubert and Günter Radons — Theoretische Physik I, Complex Systems and Nonlinear Dynamics, TU-Chemnitz

Many physical and technical systems such as shape memory alloys or certain friction models are characterized by a non-trivial hysteretic behavior with complicated subloop structure.

We study input-output-relationships and statistical properties of the system memory for a hysteretic transducer with non-local memory - represented by the Preisach operator. Our interests are input scenarios with chaotic or fractal behavior. Methods taken from time series analysis are used to compare structural properties of the input and output signal. We investigate the influence of different hysteretic nonlinearities generated by the same phenomenological model structure.
