摘要
本文介绍了磁悬浮轴承控制系统和控制原理 ,并对系统建立状态空间数学模型。采用了基于H∞控制系统的优化设计思想 ,在对轴向磁轴承H∞控制进行分析的基础上将H∞控制应用于磁轴承的控制器设计中。借助于Matlab给出了H∞控制的仿真波形。仿真和实验表明 :基于H∞理论的控制具有更好的稳定性、较强的鲁棒性和抑制扰动的能力。
The magnetic suspension bearing control system and the control theory,and the established state space mathematics model for the system were introduced. It adopted the optimization design idea based on H∞ control. And the H∞ control in the control design of magnetic bearing was applied. By the help of Matlab; the H∞ control simulation waveform was given. The simulation and experiment show: the control based on H∞ theory has the better stability, the comparatively strong robust and the ability of restrain disturbing.
