Generalized Dynamic Hysteresis Model for Improved Iron Loss Estimation of Complex Flux Waveforms
IEEE transactions on magnetics, 2019This paper presents a generalized dynamic hysteresis model for estimating the iron loss of complex flux waveforms. A versatile measurement system is developed to experimentally investigate the magnetic and iron loss properties of the studied soft ...

HYSTERESIS IN THE DYNAMICS OF EMPLOYMENT
Metroeconomica, 2012ABSTRACTIn this paper, we derive a micro model of employment demand with hysteresis whereby firms can adjust along an intensive (employment) and an extensive (hours of work) margin. A mechanism of aggregation over heterogeneous firms is used to generate the corresponding aggregate dynamics.

The magnitude of hysteresis torque band has a considerable effect on the performance of two-level direct torque control (DTC) of induction machines. The conventional DTC fails at low speed due to the poor flux regulation.

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

Due to the good dielectric, piezoelectric and ferroelectric properties, the pseudo-ternary ferroelectric single crystals Pb(In1/2Nb1/2)O3-Pb(Mg1/3Nb2/3)O3-PbTiO3 (PIN-PMN-PT) have been widely concerned and studied. In this study we found that the dynamic

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.

Preisach based dynamic hysteresis model
2004 International Conference on Intelligent Mechatronics and Automation, 2004. Proceedings., 2005In the paper, a Preisach based dynamic hysteresis model is presented as an extension of the classical Preisach model. Some mathematical properties of the model are discussed. A recursive lorm 01 the hysteresis model suitable lor real-time implementation is also developed.

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

Dynamic vector hysteresis modeling
Physica B: Condensed Matter, 2006Abstract The possibility of considering dynamic effects in three vector hysteresis models is investigated. The friction model of oriented Preisach operators which rotate due to the torque exerted by the external field, the coercive spheres model, the 3D analogue of the classical Preisach model, and a further collective model based on micromagnetic ...

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.
