Abstract：Based on the limiting hysteresis loop and numerical method, the first-order reversal curves (FORCs) generated to construct the Everett distribution function and realize the parameter identification of the Presach model with the magnetic field strength H as the input. Using numerical method to generate the FORCs can avoid the complexity and uncertainty of the experimental measurement and establish the smooth and symmetrical Everett function. At the same time, The H-based Preisach model does not involve complex numerical methods in the process of Everett function identification, which improves the computational efficiency and accuracy and enhances the applicability of the model. By using the H-based Preisach model to simulate concentric hysteresis loops and high-order reversal curves, the good agreement between the experimental and predicted results verified the accuracy and effectiveness of the model.
