A circuit model for open-loop compensation of hysteresis

2016 IEEE International Symposium on Circuits and Systems (ISCAS), 2016
Hysteresis is a nonlinear phenomenon useful whenever memory is required, but that can become annoying in applications where linearity is desired. In these cases, a possible way to reduce the inconvenience is to compensate the undesired memory effect by pre-processing the input signal through the hysteresis inverse model. In this paper, the inverse of a

Hysteresis Loops in the Microstrain Region

physica status solidi (b), 1965
AbstractPrevious papers concerning the hysteresis loops in the microstrain region have shown disagreement regarding the conditions under which closed hysteresis loops can be observed. The present paper shows that the explanation of this matter lies in the experimental procedure rather than in the type of material used.

Hysteresis Loop Analysis

IEEE Transactions on Component Parts, 1963
The apparent hysteresis loop of a square loop magnetic material is affected by winding capacitance, shorted turns, air gap, and strain. The effects of these parameters on an oscilloscopic display of the dynamic hysteresis loop are demonstrated.

Microstructure and Hysteresis Loop

2012
This chapter will discuss the micromagnetic simulation of hysteresis loops or M–H loops of magnetic thin films, based on their microstructures. The practical thin films in magnetic recording industry are all polycrystalline; therefore the microstructure of a thin film has multi-scales, such as defects, crystal grains, grain boundary, atomic symmetries ...

Hysteresis loop analytical approximation

Journal of Magnetism and Magnetic Materials, 1988
Abstract Two types of simple analytical expressions approximating the measured B ( H ) dependences of soft magnetic alloys are proposed. Their prevailence in fast and accurate fitting discrete set of ( B , H ) values is demonstrated at three types of materials.

Hysteresis loops of a bilayer superlattice

physica status solidi (b), 2007
AbstractWe apply the effective field theory with a probability distribution technique to study the effects of the interfacial coupling constant and the thickness on the hysteresis of the bilayer. A ferroelectric bilayer with an antiferroelectric interfacial coupling is investigated within the framework of the spin –1/2 Ising model.

Quantum steps in hysteresis loops

AIP Conference Proceedings, 1997
We are studying bistable quantum systems coupled to a thermal environment and driven by a strong external force. Thermal and quantum effects on the switching hysteresis are studied numerically by evaluating a time-dependent real-time double path-integral with the recently developed iterative tensor multiplication scheme for the Quasi-adiabatic path ...

A quasistatic hysteresis loop tracer

Journal of Physics E: Scientific Instruments, 1968
An instrument is described, designed for quasistatic tracing of hysteresis loops of ferroelectric capacitors. The instrument is equipped with circuits for compensation of insulation resistance and of the linear component of the capacitance of the ferroelectric sample; compensation of external spurious leakage currents is also provided for.
