Hysteresis Modelling of Soft Magnetic Materials using LabVIEW Programs

Identification and Inversion of Magnetic Hysteresis Using LabVIEW and Matlab

The sinusoidal magnetization of a sample material is difficult to achieve, since the magnetic hysteresis poses a strong nonlinearity. In order to find the proper input voltage, a feed-forward strategy with a hysteresis model identification and inversion is proposed. The classical Preisach model in the Everett formulation is used for this purpose and eddy current effects are also included. The c...

Rheological hysteresis in soft glassy materials.

The nonlinear rheology of a soft glassy material is captured by its constitutive relation, shear stress versus shear rate, which is most generally obtained by sweeping up or down the shear rate over a finite temporal window. For a huge amount of complex fluids, the up and down sweeps do not superimpose and define a rheological hysteresis loop. By means of extensive rheometry coupled to time-res...

Numerical Characterization Model of Vector Hysteresis for Magnetic Materials

The paper presents a numerical method based on Preisach model for the characterization and modelling of hysteretic magnetic materials exhibiting vector hysteresis, with acceptable accuracy, based on minimal material measurement data. The identification approach based on the Everett distribution function is a way to obtain accurate numerical solutions when the experimental data of the magnetic m...
