Numerical integration of ODEs with Preisach nonlinearity
In this article we discuss applications of the numerical integration methods to the ordinary differential equations with the Preisach nonlinearity. We use a canonical model of the iron pendulum in the magnetic field as an example of the technique. In particular we use guaranteed estimates of the integration error to rigorously prove the chaotic behaviour of the system considered. MSC 2000: Prim...
متن کاملVibration Attenuation of Nonlinear Hysteretic Structures with Fully Unknown Parameters
Natural hazards such as earthquakes have threatened the life of human beings during the history.As a consequence, the vibration mitigation of structures has caught great importance. Activecontrol of structures is one of the rapidly emerging areas in the concept of structural control. Thispaper presents a control method to deal with this subject when the dynamics of the structure ishysteretic an...
متن کاملTitle: Fast, Preisach-like characterization of hysteretic systems Authors:
Proposed is a substantially simplified, Preisach-like model for characterization of hysteretic systems, in particular magnetic systems. The main idea is to replace a two-dimensional Preisach density with just two real functions, describing in a unique way the reversible and irreversible processes. As a byproduct of our model we prove, that the major hysteresis loop alone is insufficient to prod...
متن کاملOn the Passivity of Hysteretic Systems with Double Hysteretic Loops
The Bouc-Wen hysteresis model is widely employed to mathematically represent the dynamical behavior of several physical devices, materials and systems such as magnetorheological dampers, lanthanide zirconium or aluminum oxides, mechanical structures or biomedical systems. However, these mathematical models must account for different properties such as the bounded-input bounded-output stability,...
