Research on Adaptive Evolution Architecture for Spacecraft Control System

With the continuous expansion of space missions and the growth on complexity of on-board software, improving the adaptive evolution ability of spacecraft control system becomes an important research issue. This paper focus on the adaptive evolution architecture of spacecraft software, which aims to solve the problems including software and hardware coupling, logic and information coupling, etc. And it introduces adaptive evolution layer to the architecture and enhances software flexibility through hierarchy and modularity. Besides, the dynamic parsing execution mechanism of evolution rule is proposed to provide the basic support for the dynamic adjustment through task scheduling, system parameters, and task logic. The architecture and mechanism have good application value for realizing adaptive evolution of spacecraft control system.
