摘要
以单磁铁悬浮系统为基础,根据悬浮体的运动方程,和电磁铁绕组中控制电压与控制电流的关系,得到悬浮系统的开环系统结构图,并在平衡点处建立了磁悬浮系统的状态方程,利用极点配置法,使系统满足稳定条件。在此基础上对磁悬浮系统进行了仿真分析,通过对结果的分析可得出本文的控制方法能够对磁悬浮系统进行精确和有效的稳定控制。
The single magnet suspension system as the foundation,according to the equations of motion of the suspension, and the relation between the control voltage and control current in the magnet-windings, we deduce the open-loop structure of the maglev system and establish the equation of state of the maglev system on the balance point, using pole assignment method to make the system satisfy the stable condition. On this basis we have done a simulation analysis of the maglev system, and after the analyzing the results we found that the control method in this paper can give us an accurate and effective stability control of the maglev system.
