中文摘要
      针对现有研究中缺乏指标指导深空探测器控制系统重构策略设计的量化指标的问题,本文研究了在资源受限且不可维修的条件下,面向稳定目标的深空探测器可重构性评价和自主重构设计问题。本文将在地面设计阶段考虑深空探测器控制系统的可重构性,并基于可重构性评价指标指导系统的自主重构控制方法,从设计角度提高深空探测器控制系统运行质量。首先通过左右互质分解的技术手段,基于稳定性目标,定量地给出了系统可重构性指标,描述并评价了深空探测器控制系统的重构能力;然后基于所得指标,为控制系统重构设计提供理论参考依据;最后通过数值仿真证明了该方法的有效性和正确性。
英文摘要
      In view of the lack of quantitative indexes to guide the design of reconfiguration strategy of deep-space detector control system in existing researches, this paper studies the reconfigurability evaluation and autonomous reconfiguration design of deep-space detector oriented to stable targets under the condition of limited resources and unmaintainable. This paper will consider the reconfigurability of the deep space detector control system during the ground design phase. Guiding the system’s autonomous reconfiguration strategy based on the reconfigurability evaluation index and improving the operation quality of the deep space detector control system from the design perspective. Firstly, the reconfigurability evaluation index is given quantitatively by means of left and right coprime decomposition based on the stability objective, and the control system‘s reconfiguration ability of deep space detector is described and evaluated. Then, based on the obtained indexes, the paper provides a theoretical reference for the design of spacecraft control system. Finally, the effectiveness and correctness of the method are demonstrated by the simulation example.
