摘要
悬浮电磁铁的动态模型是悬浮系统的重要组成部分,是进行悬浮系统稳定性控制的基础。该文首先扼要介绍单极悬浮电磁铁的动态模型,然后描述多极串联悬浮电磁铁的物理结构,基于有关磁路定律和电路定律研究并建立其动态模型,该模型包括电磁力―电流-间隙的动态约束方程和电流-电压的动态约束方程,它们构成了一个复杂的非线性动态系统。在此基础上设计悬浮控制器是一个十分复杂的过程,该文研究了一种基于多极串联电磁铁的动态补偿方法,该方法使多极串联悬浮电磁铁的动态耦合模型得以去耦。
The dynamic model of levitation electro-magnet is the important part of levitation system. It is also the basis of levitation system stability control. This paper introduces dynamic model of single-pole levitation electro-magnet, then describes the physical structure of multi-pole levitation electro-magnet and builds its mathematical model based on some magnetic and electric laws. This model includes force—current—gap dynamic equation and current—voltage dynamic equation. It is a complex process to design levitation controller based on the magnet dynamic model. This paper gives a dynamic compensation method which decoupled the dynamic coupled model of serial multi-pole levitation electro –magnet.
