Abstract

The invention relates to a distribution method of reconfigurable indexes of a satellite control system. The method comprises the steps of: (1) quantifying the importance, the reliability and the technology readiness of components, and calculating the weighting factors of the reconfigurable measuring indexes; (2) establishing a function tree of a satellite control system from a functional standpoint of the satellite control system; (3) aiming at the function tree established in step (2), determining the minimum family of path sets of the function tree by a downward method or an upward method; (4) using the weighting factors obtained in step (1) and the minimum family of path sets R obtained in step (3) to distribute the reconfigurable measuring indexes. Based on the reconfigurable model of the function tree, the distribution method realizes the distribution of the reconfigurable design indexes from the system to the components, thereby providing a basis for the reconfigurable design of satellites.

Description

technical field

[0001] The invention relates to the aerospace field, in particular to a method for allocating reconfigurability indexes of a satellite control system, which realizes the allotment of reconfigurability design indexes from systems to components. Background technique

[0002] With the development of science and technology, satellites have played an irreplaceable role in various fields such as national defense, military, communications, and meteorology. In order to cope with various failures that may occur in satellites in orbit and improve the quality of operation, it is necessary to ensure that effective measures are taken in time to minimize the impact of failures after failures occur. This is to overcome the inherent reliability of products at the system level and improve the reliability of satellite operations. Effective means of sex and life extension. Since satellites cannot be maintained on-orbit, generally only reconfiguration can be used to restore sys...
