针对 Preisach 标量模型的磁滞算子几何叠加的原理，提出了基于一阶回转线进行磁滞特性研究的新模型。该模型基于 Preisach 模型的同余性和一阶回转曲线数据建立相应的磁滞数学模型，可以对铁磁材料的高阶回转曲线进行准确仿真。该模型实现简单，避免了传统数值方法求解 Preisach 分布函数必须进行两次求偏导和双重积分计算的复杂过程，并且提高了磁滞数学模型仿真精度。仿真结果与文献中测量结果相吻合，验证了该模型的准确性及有效性。

A new Preisach model based on the first-order reversal curves was proposed in this paper, according to the geometric superposition principle of scalar Preisach model. The corresponding mathematic hysteresis model is set up based on the congruency of the Preisach model and the first order reversal curves data. The high-order reversal curves are simulated accurately by using the proposed model, which is easily implemented. Moreover, it is not necessary to perform second-order partial derivation and double integration required by traditional method. The simulation agrees with measurement, proving effectiveness of the proposed model in this paper.
