| 摘 要： | 简要介绍了经典Preisach理论,提出了一种用于仿真铁心磁化过程的新型数字化模型。该模型通过分离Preisach函数的变量,得到了铁心磁化轨迹的表达式;采用堆栈操作来模拟铁心对磁场强度极值的记忆和遗忘,以此来确定铁心磁化轨迹的位置。仿真和实验结果比较表明,新模型实现简便、仿真准确,具有较高的精度,且能准确反映铁心磁化轨迹的特点。

| Abstract: | This paper summarizes the characteristics of magnetic trajectory and gives an introduction ot Preisach theory. And then, presents a new digital model of magnetic core. The new model gets expressions of the magnetic trajectory branches by separating the variables of Preisach function; and determines the position of magnetic trajectory by simulating remembering and forgetting extremes of magnetic field intensity of magnetic core with stacks opera- tion. Comparison between simulation results and experimental results shows that the new model has high precision. |
