Preisach Hysteresis Modeling and Applications
Preisach modeling, long known in the area of magnetics, has introduced mathematical abstraction to the modeling of the highly nonlinear and complex phenomenon of hysteresis. The 2D Preisach-type models presented here, departing slightly from the classical formulation, waive some of its limitations while maintaining the major advantages of simplicity and speed in calculations. Results on differe...
متن کاملTHE INFLUENCE OF STRAIN-RATE, AMPLITUDE AND TEMPERATURE ON THE HYSTERESIS OF A PSEUDOELASTIC Cu-Zn-Al SINGLE CRYSTAL
The hysteresis loop, described during the formation of stressinduced pseudoelastic martensite in a Cu-Zn-A1 betaphase single crystal, was studied as a function of strain-rate, deformation amplitude and temperature. The aPtm, the stress at which the transformation starts at a given constant temperature, is strain-rate independent but the hysteresis described by the stress-strain curve shows a ma...
متن کاملStability of control for the Preisach hysteresis model
The motivation for this research arises from recent interest in actuators made from \smart mate-rials" such as shape memory alloys and piezoceram-ics. One common characteristic among these new materials is that they exhibit complex hysteresis non-linearities. The input-output nature of the Preisach model of hysteresis results in a simple model for which identiication strategies are known, and i...
متن کاملA compressive sensing-based approach for Preisach hysteresis model identification
The Preisach hysteresis model has been adopted extensively in magnetic and smart materialbased systems. Fidelity of the model hinges on accurate identification of the Preisach density function. Existing work on the identification of the density function usually involves applying an input that provides sufficient excitation and measuring a large set of output data. In this paper, we propose a no...
متن کاملA Novel Preisach Based Neural Network Approach to Hysteresis Non-Linearity Modeling
In some systems with hysteresis behavior like Shape Memory Alloy (SMA) actuators and Piezo actuators, we essentially need an accurate modeling of hysteresis either for controller design or performance evaluation. One of the most interesting Hysteresis non-linearity identification methods is Preisach model in which hysteresis is modeled by linear combination of elemental operators. Despite good ...
