动静隔离、主从协同控制超高指向精度、超高稳定度卫星
摘要：
本发明提供了一种动静隔离、主从协同控制超高指向精度、超高稳定度卫星，其包括布置在平台舱与载荷舱之间的非接触磁浮机构；非接触磁浮机构包括相匹配的动子和定子；动子安装于平台舱，定子安装于载荷舱；载荷舱与平台舱之间通过动子和定子实现动静隔离。以空间上动静隔离，控制上主从协同的全新思想和方法，采用完全位姿解耦构型和滑模层控制思想，利用高精度、高带宽非接触磁浮机构，实现卫星姿态指向精度优于5×10-4度、姿态稳定度优于5×10-6度/秒的超高精度，彻底解决“双超”技术瓶颈，实现了载荷姿态的完全可测可控。
摘要（英）：

The invention provides a satellite with ultrahigh pointing accuracy and ultrahigh stability under dynamic-static isolation and principal-subordinate cooperative control, which comprises a non-contact magnetic-suspension mechanism disposed between a platform cabin and a load cabin, wherein the non-contact magnetic-suspension mechanism comprises a rotor and a stator which are matched; the rotor is installed in the platform cabin, and the stator is installed in the load cabin; and the dynamic-static isolation between the load cabin and the platform cabin is realized by the rotor and the stator. By adopting a brand-new idea and a brand-new method of the spatial dynamic-static isolation and the principal-subordinate cooperative control, applying a control idea based on a complete pose decoupling configuration and a slip form layer, and using the non-contact magnetic-suspension mechanism with high accuracy and high bandwidth, the satellite pose pointing accuracy is higher than 5*10-4 DEG/SEC, the pose stability is higher than the ultrahigh accuracy of 5*10-6DEG/SEC, a technical difficulty about the ''ultrahigh accuracy and ultrahigh stability'' is thoroughly solved, and a load pose can be completely measured and controlled.
