航天器控制系统可重构性的内涵与研究综述

Connotation and Research of Reconfigurability for Spacecraft Control Systems: A Review

可重构性设计是提高航天器在轨运行质量的有效途径,可以从系统层面克服航天器控制系统固有可靠性不足、星上资源受限以及在轨故障不可维修等缺陷,目前已引起控制理论和航天器控制工程等领域的高度重视与广泛关注.本文首先结合航天器控制系统的固有特点,具体介绍可重构性的研究意义与概念内涵.然后从评价与设计两方面,详细梳理航天器控制系统可重构性的研究内容与研究现状.最后对目前可重构性研究领域中存在的一些问题以及未来可能的发展方向进行深入探讨.

Since control reconfigurability design can overcome the inherent deficiency of reliability insufficiency, limitation of resource and unrepairability of fault for spacecraft control system, it is the fundamental approach to improve the operational quality of on-orbit spacecraft, which has attracted intensive attention from both control theory field and spacecraft control engineering field. First of all, the research significance, connotation and research range of reconfigurability for spacecraft control system are described in detail. Then, the current research status of control reconfigurability is summarized from the aspects of reconfigurability evaluation and reconfigurability design. Finally, problems to be solved are presented and some countermeasures and suggestions are put forward.
