摘　　要：对新一代大型运载火箭控制系统采用的"双通道总线+三冗余"全数字系统架构进行比对分析,并基于此架构开展动态可重构技术研究,提出基于控制分配技术的可变结构系统架构重构策略、三冗余总线控制器重构策略、惯组三机冗余与单机多表相结合的重构策略。系统冗余配置结合重构策略,实现了对飞行异常状态的智能故障识别与动态重构,提高了系统的容错能力及飞行可靠性,可靠性预计结果达到国际一流水平。The system architectures of launch vehicle at home and abroad are investigated,and the digital system architecture of the new generation of large-scale launch vehicle control system is analyzed,which is consisting of dual-channel digital bus and triple-modular redundancy terminal.Based on this architecture,dynamic reconfigurable technology is studied.The strategies of allocation in different scenarios are proposed,such as the system architecture reconfigurable strategies based on allocation technology,the triple-modular bus-controller reconfigurable strategies,the triple-modular redundancy inertial device and multi-sensor data fusion reconfigurable strategies.Through the combination of redundancy configuration and reconfigurable strategies,the control system may automatic identify the failure and dynamically reconfigure if the flight is abnormal.The system fault tolerance and reliability has been effectively improved.The evaluation result indicates that the flight reliability of the large-scale launch vehicle control system has achieved the world class level.
