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 کاملParametrised Preisach Modelling of Hysteresis in High Temperature Superconductors
We present a parametrised Preisach-type model that describes the hysteresis exhibited by the high temperature superconductors (HTSC); hysteresis is the main cause for losses in the subcritical domain. The parametrised model, in combination with electrical measurements, is independent of geometry, number of laments and other physical measures, and is identiied by a novel method that uses electri...
متن کاملModeling Rate-Dependent and Thermal-Drift Hysteresis through Preisach Model and Neural Network Optimization Approach
Smart material actuators like Piezoelectric(PZT) are widely used in Micro/Nano manipulators, but their hysteresis behaviors are complex and difficult to model. Most hysteresis models are based on elementary quasistatic operators and are not suitable for modeling ratedependent or thermal-drift behaviors of the actuators. This work proposes a Preisach model based neurodynamic optimization model t...
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 کاملMathematical Modeling of the Temperature-Dependent Growth of Living Systems
In this investigation a non-equilibrium thermodynamic model of the temperature dependent biological growth of a living systems has been analyzed. The results are derived on the basis of Gompertzian growth equation. In this model, we have considered the temperature dependent growth rate and development parameter. The non-equilibrium thermodynamic model is also considered for exploring the variat...
