摘　　要：传统的余度故障处理方式会导致飞控计算机系统在出现局部故障时出现安全性快速降级,剩余的余度再出现问题时将危及飞行安全和任务的完成。故障余度重启恢复同步将有效提高飞控计算机的可靠性。通过分析系统正常上电的余度同步过程和重启余度上电过程,研究了单通道故障重启同步过程和双通道故障重启同步过程,从而提高飞控系统的可靠性,保证了飞行控制系统的品质。The traditional redundancy fault handling method would lead to the safety degradation of flight control computer system in the case of local faults.When the residual redundancy problems occur again,the flight safety and the completion of the mission will be endangered.The reliability of flight control computer can be effectively improved by fault redundancy restart and recovery synchronization.By analyzing the redundancy synchronization process of system power-on and restart,the single-channel fault restart synchronization process and dual-channel restart synchronization process are studied,so as to improve the reliability of the flight control system and ensure the quality of the flight control system.
