磁悬浮双级惯性稳定（MDIS）系统是一种新提出的系统，它结合了传统的两轴框架组件和具有游标倾斜能力的五自由度磁轴承，对悬浮光学仪器的视点进行双级稳定。与传统的双级系统相比，磁悬浮双级系统由于磁力的负位置刚度而表现出不同的特性，这在双级控制系统中引入了额外的耦合。本文从频域分析的角度分析了耦合对系统性能的影响，包括扰动抑制、细级饱和和粗级结构共振抑制。讨论了各种控制策略的区别，包括堆积（PU）、稳定跟随（SF）和稳定补偿（SC）。提出了磁悬浮双级系统设计的若干原则。本文还提出了一种通用的流程，该流程将导致在高性能和复杂性之间取得平衡的经济有效的设计。最后，给出了一个仿真实例来说明本文的论点。
Maglev dual-stage inertially stabilization (MDIS) system is a newly proposed system which combines a conventional two-axis gimbal assembly and a 5-DOF (degree of freedom) magnetic bearing with vernier tilting capacity to perform dual-stage stabilization for the LOS of the suspended optical instrument. Compared with traditional dual-stage system, maglev dual-stage system exhibits different characteristics due to the negative position stiffness of the magnetic forces, which introduces additional coupling in the dual stage control system. In this paper, the coupling effect on the system performance is addressed based on frequency-domain analysis, including disturbance rejection, fine stage saturation and coarse stage structural resonance suppression. The difference between various control strategies is also discussed, including pile-up(PU), stabilize-follow (SF) and stabilize-compensate (SC). A number of principles for the design of a maglev dual stage system are proposed. A general process is also suggested, which leads to a cost-effective design striking a balance between high performance and complexity. At last, a simulation example is presented to illustrate the arguments in the paper.
