单轴磁悬浮系统控制器的仿真研究

介绍了单轴磁悬浮系统的组成及基本工作原理，通过线性化方法建立了系统的力学模型，并基于此模型设计了闭环控制器的四种控制方案。通过对这四种控制方案在受到阶跃扰动时的仿真研究，分析了它们的稳态情况及抗干扰能力，得出了性能比较良好的控制方案，并相应给出了计算机的仿真结果。

A Simulation Study of Controller for Single-axis Electromagnetic Suspension System

This paper introduces components of single-axis electromagnetic suspension system and basic work principle, establishes systematic mechanical model by linearization method. On the basis of that, four kinds of control methods of closed-loop controller are designed. By simulation of these control systems under the situation of step disturbance, the ability of anti-interfere of these control methods is analyzed and can be drawn out the better model of controller. At last, the result of computer simulation is drawn on the paper.
