摘要
针对轴承－转子－控制器组成的主动型电磁轴承系统，分析了其控制系统的稳定性，提出了具有实际意义的三种刚度及阻尼定义．计算机辅助分析提供了分析电磁轴承系统动态性能及复刚度的理论依据．所得结果均和一个五自由度控制磁悬浮轴承系统的实验结果相一致．
The stability of controlling system for active magnetic. bearing system (AMBsystem) composed of bearing, rotor, and controller is analysed and three practical definitions of stiffness and damping are, then, advanced. The theoretical basis for analyzing dynamicperformance of AMB system and complex stiffness is provided by CAA. The theoreticalanalysis and experimental results of five-degree-of-freedom electromagnetic levitated systemcoincide with each other.
