Preisach Modelling: Symmetry Implementation and Frequency Analysis

The paper contains an analysis of the classical Preisach Model from a symmetry and a frequency point of view. Increasing and decreasing inputs have no fundamental difference, which leads to a simplified implementation by changing indices. Symmetry implies that the fully demagnetised state can be taken into account without approximations. A frequency analysis demonstrates that all odd and only odd harmonics of the fundamental input frequency are transferred to the output. As a consequence an estimation method for the Preisach Model weighting function from sinusoidal input is suggested.
