摘　　要：在分析磁悬浮轴承(AMB)数学模型的基础上,针对磁悬浮轴承非线性、不稳定、易于振荡等问题,提出了基于内模控制的研究策略。对于实时在线控制系统,内模控制不依赖被控对象的准确模型,具有操作简便、易于控制等优点。Matlab仿真结果表明,该控制策略具有快速反应速度,对于转子运动的稳定性要求显示了良好性能。Based on the analysis of the magnetic suspension bearing mathematical model and due to its nonlinearity,unstability and easy oscil ation,this paper puts forward the strategy based on the internal model control research. For the real-time on-line control system,the internal model control which does not rely on the accurate model of the control ed object is characteristic of easy operation and control. Matlab simulation results show that the control strategy is of fast response speed,and perfect rotor movement stability.
