摘要
航天器无拖曳控制是利用推进器产生的推力来补偿航天器受到的非保守力使其跟随检验质量运动,是获得超低微重力水平卫星平台的重要途径,是空间基础物理、微重力测量、地球科学和卫星导航等实验研究的关键技术之一。结合空间引力实验和卫星重力测量计划,阐述航天器无拖曳控制的发展历程和基本工作原理,对无拖曳控制系统的组成和关键技术进行详细讨论,最后简要概括目前无拖曳控制器的设计方法。
Drag-free control, which is used to compensate the non-conservative forces acting on a spacecraft to follow the test mass using thrusters, is an important way to obtain an ultra-low disturbances spacecraft platform, and also one of the key technologies for space fundamental physics, microgravimetry, Earth science and satellite navigation. Developmental history and fundamental operation concept of the drag-free control technology are reviewed combined with space gravitational experiments and gravity satellites missions, and then systematic configuration and key points of drag-free contrul systems are discussed in detail. Finally, several actual drag-free control algorithms and controllers are simply summarized
