Simple Preisach Model Implementation

We can utilize a simple Preisach model to characterize the input-output relationship of piezoelectric ceramics. The Preisach model effectively describes nonlinear behaviors in various physical phenomena including magnetic, electrical, mechanical, and thermal systems. In MATLAB implementation, this model can be programmed using differential equations or discrete operators to capture hysteresis effects, typically involving weight function distributions and relay operators. Key implementation aspects include defining the Preisach plane discretization, implementing hysteresis operators through switching thresholds, and performing parameter identification through experimental data fitting. By employing the Preisach model, we gain deeper insights into piezoelectric ceramic properties and behaviors, enabling accurate prediction and control of system responses. This modeling approach finds extensive applications across multiple disciplines including electronic engineering, materials science, and physics.
