英文摘要： Reliable operation of attitude control systems(ACS) is the precondition that missions of satellite experiments can be carried out. However, the extreme environment of space can easily cause the high occurence of component faults. To improve ACS's on-orbit fault-handling capability, the improvement of system's reconfigurability design level is an effective approach, which predicts and evalutes the reconfigurability of the system with reasonable and proper usage of onboard resources, in addition to the proposal of effective on-orbit reconfigurable strategies. This project focuses on the requirement for satellite reliability development, with satellite attitude control system targeted on, the concept of reconfigurability is studied, the evalutaion indices for reconfigurability is proposed and the mathematical description of it is studied; then the criteria of reconfigurability prediction is studied and the framework of reconfigurability prediction and evaluation is established. This project is of challenges as well as innovation, the study results of which can not only provide valid theoretical support and decision-making basis for the accomplishment of on-orbit reconfiguration of satellite, but also lay a foundation for the further study of reconfigurability design, thus it possesses strong general applicability
