Use of the Preisach and L2P Models Together for Greater Confidence in Hysteresis Curves at Different Frequencies

This work proposes a new approach for the observation of frequency hysteresis curves. The idea developed is based on the joint use of two hysteresis models to observe the response and compare it. Thus, Preisach and L2P (Limiting Loop Proximity) hysteresis models were simulated, comparing their responses at different frequency values. The results presented show slight discrepancies due to its form of assessment, which in the classic Preisach model is totally irreversible and the L2P model has a small portion that causes it to have a percentage of reversibility. An approximation is made so that both can diminish their differences so that with the same field applied the results obtained have a better precision allowing to obtain hysteresis curves with greater reliability without the need to carry out other studies other than the application of the two models.
