摘　　要：深空探测任务对星载控制计算机的智能性、环境适应性和自主性提出新的需求。介绍目前星载控制计算机容错方法的进展情况,提出可进化硬件容错这种可用于星载控制计算机容错设计的智能容错方法,给出该方法的3种实现结构,即并行结构、串行结构和具有故障检测功能的串行结构,并对各种结构进行分析和比较。最后,用仿真验证平台验证了串行结构的可行性和容错性。In the deep space exploration mission, on-board computer （OBC） for satellite control system has more new requirements, such as intelligence, adaptability and self-determination capability. The state of arts of OBC＇ s fault-tolerance methods is introduced. An intelligent fault-tolerance method called evolvable hardware （EHW） fault-tolerance used in the fault-tolerance design of OBC is presented. Three architectures to implement EHW fauh-tolerance, which are parallel architecture, serial architecture and serial architecture with fault detection, are brought forward. Moreover, analysis and comparison are made among those architectures. Finally, a simulation validation platform is implemented so that the feasibility and fault-tolerance capability of serial architecture has been validated.
