摘要
首先对磁悬浮控制系统的数学模型进行分析，经过合理的线性化，建立了系统的状态空间模型，在此基础上进行了ＰＩ状态反馈控制器的设计。对控制器数字仿真的结果表明，ＰＩ状态反馈设计方法能够得到动备性能优良、稳态无差的控制器，并且悬浮位置输出可直接由参考输入端给定。
The device for magnetic suspension is analyzed, and the accurate math model of the device isset up. By linearizing, the author deduces the state equation of the magnetic suspension system from the mathmodel, On the base of system model, this paper design the PI states feedback controller. The simulation ofthis controller proved that the PI states feedback control has nice dynamic and static performance. The staticstates error is zero, and the position of suspended body can be set by the reference input.
