电磁力的精确建模及参数辨识

Accurate electromagnetic modeling and parameter identification

传统磁悬浮平台电磁铁的电磁力模型一般是在理想情况下建立的,如果需要建立精确的模型,漏磁通、气隙边缘效应等影响不能理想化。在考虑漏磁通、气隙边缘效应等因素的情况下,对某一具体磁悬浮平台进行精确建模。基于此模型,对平台进行悬浮实验,并采集到输入、输出数据,进行参数辨识,修正理论模型。

The electromagnetic force model of traditional magnetic suspension platform is generally created in an ideal situation,but when need to build more accurate models,leakage flux,gap edge effect and other effects can not be idealized.Considered the case of the above factors on a specific platform,to build an accurate modeling of magnetic levitation,then collected input and output data on this magnetic suspension platform based on this model,and did parameter identification,to modify the theoretical model.
