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 ...

Modified Dynamic Preisach Model for Hysteresis
AIAA Journal, 2009We propose a dynamic hysteresis model developed using a modified version of the Preisach hysteresis operator to simulate the change in electrical resistance with strain in conductive polymer nanocomposites. Result of the conductivity test on a conductive polymer nanocomposite sample has been presented to show its hysteretic variation of resistance with

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.

Role of hysteresis in stomatal aperture dynamics
Physical Review E, 2013Stomata are pores responsible for gas exchange in leaves. Several experiments indicate that stomata synchronize into clusters or patches. The patches' coordination may produce oscillations in stomatal conductance. Previous studies claim to reproduce some experimental results.

Dynamics of a New Hysteresis Memristor CNN
2020 European Conference on Circuit Theory and Design (ECCTD), 2020In this paper we study a new class of hysteresis memristor CNN (HM-CNN). The model under investigations contains a simpler state equation with hysteresis operator in the feedback circuit and resonant tunnel diode in the output. The dynamics is studied in different regions depending on hysteresis nonlinearity.

Dynamic Response of Nonlinear Oscillators With Hysteresis
Volume 6: 11th International Conference on Multibody Systems, Nonlinear Dynamics, and Control, 2015The nonlinear features of the steady-state periodic response of hysteretic oscillators are investigated. Frequency-response curves of base-excited single-degree-of-freedom (SDOF) systems possessing different hysteretic restoring forces are numerically obtained employing a continuation procedure based on the Jacobian of the Poincaré map.

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 ...

Dynamic modeling of magnetic hysteresis
Journal of Spacecraft and Rockets, 1970Magnetic hysteresis rods have been used successfully for damping the attitude motions of passively stabilized near-Earth satellites. This paper describes the implementation of a model of magnetic hysteresis that is suitable for digital computer simulations of such motions.

A hysteresis-based chaotic circuit: dynamics and applications
International Journal of Circuit Theory and Applications, 1999A chaotic circuit based on a hysteretic mechanism is presented and analyzed. In Section 2, the circuit is presented, and a qualitative analysis of its behaviour is made. In Sections 3 and 4, the dynamic behaviour of the circuit is studied in depth, and the results of some numerical simulations are reported.

Dynamic programming for systems with hysteresis
Physica B: Condensed Matter, 2001Abstract We introduce a novel type of dynamic programming equations for controlled differential equations with hysteresis on the control. The novelty of our approach is that we use Hamilton–Jacobi functions with one of the variables being set-valued, corresponding to the active set on the Preisach plane.
