| 摘 要： | 磁悬浮系统降阶参数自校正控制,针对直接状态反馈法不足,使闭环系统的动态性满足调节时间和超调量等要求.其降阶指把电流环时间常数调整到尽量小,低频信号段可等效为普通比例环节.该方法以电磁铁动力学和电磁线圈的电压平衡方程,建立磁悬浮系统基本模型,利用劳斯判据求出常规PID控制参数并应用到磁悬浮系统的控制参数稳定.

| Abstract: | Aiming at the shortage of the direct state feedback method, Self-adaptive control of rank-reduced parameter for magnetic suspension system make the dynamic state of closed-loop system satisfies the requirements of time and quantity of regulation. The intension of reduce rank is that the time constant of current-ring is regulated to the best of minimum, and low frequency signal is equated to common proportional component. The base model of magnetic suspension system was found based on voltage balance equation of electromagnet dynamics and the electromagnet coil. The range of the ordinary PID control parameter was extracted with Louts criterion, and the PID control parameters are used as the control parameters in stability range of magnetic suspension system. |
