Scaling law for dynamical hysteresis
Physical Review Letters, 1990A one-dimensional theory of dynamical hysteresis in periodically switched bistable systems is formulated. The predictions of the theory are tested and verified by experiments on a bistable semiconductor laser. We find that the increase of the area of the hysteresis loop scales as the two-thirds power of the switching frequency.

Dynamics of a simple hysteresis network
Proceedings of IEEE International Symposium on Circuits and Systems - ISCAS '94, 2002In order to approach the explication of rich dynamics from a large scale nonlinear network, this paper analyses a continuous time hysteresis network whose cross connection is uniform. This system has only two parameters. Applying an efficient piecewise linear technique for a binary hysteresis element, we can clarify the existence condition of periodic ...

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 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

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.

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.

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

Shape fluctuation-induced dynamic hysteresis
The Journal of Chemical Physics, 2012We consider a system of Brownian particles confined in a two-dimensional bilobal enclosure whose walls are driven in time periodically by an external perturbation. The response of the particles under shape modulation is characterized by a relaxational delay which results in a non-vanishing area of the response function—field loop, response function ...

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.
