Prandtl-Ishlinskii hysteresis models for complex time dependent hysteresis nonlinearities

We introduce a new class of time dependent hysteresis models by combining to characterizea class of complex time dependent hysteresis nonlinearities in smart actuators. The analytical inversion fo...

Reduction in energy dissipation rate with increased effective applied field

field can exhibit rate-independent or rate-dependent hysteresis. An energy dissipation rate in a superconductor placed in a time varying magnetic field depends on its waveform and type of hysteresis which...

Asymptotic Description of the Time and Temperature Hysteresis in the Framework of Landau-Khalatnikov Equation

The main objective of this work is to study and interpret the time dependence of the ferroelectric polarization in the case of a periodic variation of the electric field relaxation time of a ferroelectric. For the process d...

Inverse rate-dependent Prandtl-Ishlinskii operators and applications

In the past years, we observed an increased interest in rate-dependent hysteresis models to characterize complex time-dependent nonlinearities in smart actuators. A natural way to include rate-dependence t...

Nonlinear time domain transformer model assessment

The dependence of current effective values on applied harmonic voltage of unloaded transformer cannot be used for time domain analysis. Because of the unavailability of the time domain measured values authors has developed ...

Difficulties Caused by Magnetic After-effect during Identification of the Preisach Hysteresis Model Weighting Function

The time dependence of the magnetic hysteresis caused by thermal activation over an energy barrier is called after-effect, magnetic viscosity, or magnetic relaxation. Magnetic after-effect influences the hysteresis...

Inverse parameter-dependent Preisach operator in thermo-piezoelectricity modeling

Hysteresis is an important issue in modeling piezoelectric materials, for example, in applications to energy harvesting, where hysteresis losses may influence of the underlying hysteresis operator.Moreover, hysteresis

An inversion formula for a Prandtl-Ishlinskii operator with time dependent thresholds

We extend the well-known inversion result for Prandtl-Ishlinskii operators to the case of time dependent thresholds. The exact inversion formula is shown to hold under the condition that the distances between the thresholds do not d...
