摘要
Jiles-Atherton(JA)模型由于具有计算简单、稳定方便、物理意义明确的优点,在压电材料、磁致伸缩材料、形状记忆合金为代表的新型智能材料的建模方面具有重要应用。但JA模型具有一些本质弱点,比如,它是一个非物理的模型,而且由于是标量模型,不能处理各向异性。针对这些缺点许多作者做了大量改进工作。本文将对这些工作简单综述。还介绍了JA模型的2个主要应用:磁滞控制和磁二相系统的建模;介绍了JA模型以及JA逆模型的基本方程以及磁滞系统的逆补偿控制的基本概念和方法。对于JA模型用于磁二相系统的建模的优缺点也作了评述。
The Jiles-Atherton （JA） model has been applied in the modeling for new smart ma- terials, such as piezoelectric materials, magnetostrictive materials, shape memory alloy, etc. , due to its advantages of simple, stable and physical characteristics. At the same time, the JA model has several essential weaknesses. For instance, it is a non physical model and it can not handle the anisotropy since it is scalar. Many improvements have been made to address these shortcomings and a brief review was presented. Two main applications of the JA model, for hys teresis control and magnetic two-phase system modeling, were also described. The basic concepts of inverse compensation and control were introduced and the equations of the JA model and the inverse JA model were given. The advantages and disadvantages of the JA model for modeling of two-phase magnetic systems were also commented.
