系绳卫星控制系统可重构性评价指标

针对系绳卫星控制系统，展开系绳卫星控制系统可重构性评价指标的研究。首先建立了由三个子卫星组成的系绳卫星控制系统；然后针对该模型进行可重构性评价，给出可重构性评价指标，该指标不仅描述了系统的重构能力，同时还强化了可重构性评价对重构策略指导的作用，体现了重构设计对可重构性评价方法的依赖性。最后通过数值算例，分析了系绳卫星的可重构性指标，并对故障后的系统重新设计重构控制律使其保持稳定。

Evaluation Index of Reconfigurability of Tether Satellite Control System

Aiming at tethered satellite control systems, the research on reconfigurability evaluation indicators of tethered satellite control systems was carried out. Firstly, a tethered satellite control system composed of three sub satellites was established; Then, a reconfigurability evaluation is conducted for the model, and a reconfigurability evaluation index is given. This index not only describes the system''s reconfiguration ability, but also strengthens the role of reconfigurability evaluation in guiding the reconfiguration strategy, reflecting the dependency of reconfiguration design on the reconfigurability evaluation method. Finally, through the numerical examples, the reconfigurability index of the tethered satellite is analyzed, and the system after the failure is redesigned to keep it stable.
