A viscous-type dynamic hysteresis model (DHM) is developed. The DHM is compatible with static underlying model of any type and nature (Preisach or non-Preisach). The distinguishing features of the DHM are its arbitrary frequency dependence and the ability to control the shape of the dynamic hysteresis loop. The numerical method for the incorporation of

Hysteresis in structural dynamics
Physica B: Condensed Matter, 2012Abstract In this paper the Preisach hysteresis model is applied to determine the dynamic behavior of a steel column with mass on the top and loaded by an impulse force. The column is considered as a rigid element, while the fixed end of the column is modeled with a rotational spring of hysterestic characteristic.

A measuring procedure has been developed to determine the hysteresis loss as function of the magnetizing frequency. It was applied to single crystal frames of iron-silicon and tape wound cores of that alloy and metallic glasses. Actually the hysteresis loss energy is frequency dependent and to an extent that must not be neglected if the dynamic loss ...

Systematic Hysteresis Analysis for Dynamic Comparators
Journal of Circuits, Systems and Computers, 2019Comparator hysteresis is a memory phenomenon allowing outputs maintaining their past stable states until the input difference overcomes a given threshold voltage. In some applications, such as ADCs and memories, hysteresis is a deterministic error that should be minimized.

Dynamic hysteresis in magnetostrictive amorphous microwires
IEEE Transactions on Magnetics, 2002Summary form only given. Amorphous magnetostrictive wires exhibit very rapid bistable magnetisation reversal (large Barkhausen jump). This property makes them unique for applications in security sensors and pulse generators. As operational frequencies become progressively higher, there is an interest in studying the magnetisation reversal in bistable ...

Entropic dynamical hysteresis in a driven system
Physical Review E, 2012We show that the application of a time periodic field driving a Brownian particle between the two lobes of a two-dimensional bilobal enclosure results in a hysteresis loop in the variation of integrated probability of residence of the particle as a function of the field.

Dynamical aspects of the adsorption hysteresis phenomenon
Magnetic Resonance Imaging, 2007Equilibrium and nonequilibrium transport properties of adsorbates in mesoporous Vycor porous glass have been experimentally studied using nuclear magnetic resonance techniques. With the known geometrical characteristics of porous glass and with measured self-diffusivities, transient sorption curves have been quantitatively compared to those predicted ...

The static hysteresis model which is based on Frohlich equations is extended to simulate the dynamic B-H behavior including hysteresis. In order to describe the dynamic model, the following conditions are required: the magnetizing curve, the relationship between H/sub c/ with H/sub m/ (or B/sub m/) and B/sub r/ with B/sub m/ (or H/sub m/); and the fact

The neural dynamics for hysteresis in visual perception
Neurocomputing, 2011The hysteresis in the perception has been observed in many perceptual experiments, but little is known about the underlying dynamical mechanism. We simulate a visual discrimination task, as an example of hysteresis in the perception, using a spiking neuron network and the corresponding slow dynamic system.

Generalization of a model of hysteresis for dynamical systems
The Journal of the Acoustical Society of America, 2002A previously described model of hysteresis [J. C. Piquette and S. E. Forsythe, J. Acoust. Soc. Am. 106, 3317–3327 (1999); 106, 3328–3334 (1999)] is generalized to apply to a dynamical system. The original model produces theoretical hysteresis loops that agree well with laboratory measurements acquired under quasi-static conditions.
