摘　　要：准确且快速地模拟软磁材料的磁滞特性是电机、变压器等电力设备电磁场仿真及其优化设计等工作可靠展开的基本前提。然而,经典Preisach磁滞模型因包含了复杂的双重积分运算而难以达到上述要求,而现有唯一的纯解析Preisach模型存在推导失误、无法通用等问题。为此,针对该解析Preisach模型的问题,推导正确的Everett函数解析表达式,并基于Preisach基本原理,分析在其基础上考虑可逆磁化分量的本质原因,继而提出首个正确且通用的解析正Preisach模型。将仿真结果与实测结果进行对比,验证所提模型的精度。Simulating the hysteresis characteristic of soft magnetic materials accurately and quickly is crucial for the electromagnetic field simulations,optimal designs and other aspects of motors,transformers,and etc.However,the classical Preisach hysteresis model involves complex double integral operation,making it difficult to meet the above requirment,and the only proposed analytical Preisach model has the problems of deduction mistakes and being not generic.To resolve these issues of the analytical Preisach model,the correct analytical Everett function is thereby deduced.Based on the analysis of Preisach basic principle,the key cause for considering the reversible magnetization component is thus analyzed,and accordingly a correct and general analytical forward Preisach model is proposed for the first time.The simulated hysteresis loops are compared sufficiently with the measured ones to verify the accuracy of the proposed model.
