A New Object-Oriented Simulation Tool for Modeling Preisach-Based Magnetic Hysteresis Nonlinearities
Author:
Abstract: The Preisach theory of hysteresis is regarded by many experts to be the most accurate physical description of hysteresis behavior, especially in ferromagnetism. Unfortunately, its practical applications and accessibility to students and researchers are limited due to its complex formulation and numerical implementation. Instead, simpler and less accurate hysteresis models or anhysteretic single-value nonlinear models are often employed. This paper proposes a new and relatively simple object-oriented model representation for Preisach theory in MATLAB-Simulink. The developed hysteresis block is highly customizable for modeling complex dynamical systems and is also ideal for use in educational courses to allow students to simulate and further their understanding of ferromagnetism and hysteresis behavior in nonlinear systems.
