摘要

本文提出了一种标量 Preisach 模型的识别方法,以考虑分布函数识别过程中可逆磁化的影响。通过从测量数据中剔除可逆成分的影响来重新考虑识别过程,用纯不可逆成分来识别普雷萨赫分布函数。这样,极限磁滞环和内部对称小磁滞环的模拟精度都得到了保证。此外,通过采用混合离散法的离散普雷萨赫平面,改进后的普雷萨赫模型可以更高效地计算不可逆磁通密度分量。最后,将提出的方法结果与传统方法和考虑到可逆磁化的传统方法进行了比较,并通过爱泼斯坦框架对 B30P105 电工钢的实验室测试进行了验证。

An Improved Preisach Distribution Function Identification Method Considering the Reversible Magnetization
This paper presents an identification method of the scalar Preisach model to consider the effect of reversible magnetization in the process of distribution function identification. By reconsidering the identification process by stripping the influence of reversible components from the measurement data, the Preisach distribution function is identified by the pure irreversible components. In this way, the simulation accuracy of both limiting hysteresis loops and the inner internal symmetrical small hysteresis loop is ensured. Furthermore, through a discrete Preisach plane with a hybrid discretization method, the irreversible magnetic flux density components are computed more efficiently through the improved Preisach model. Finally, the proposed method results are compared with the traditional method and the traditional method considering reversible magnetization and validated by the laboratory test for the B30P105 electrical steel by Epstein frame.
