摘　　要：电传控制系统是一个全时间、全权限的"电信号+控制增稳"的飞行操纵系统,解决了稳定性与操纵性之间的矛盾,获得了稳定性和机动性的理想融合。应用余度技术是提高系统可靠性、容错能力的有效手段。本文结合某型飞机四余度数字电传控制系统,详细描述其余度管理策略,最大限度地提高系统的资源利用率,进行准确的故障诊断、重构、隔离、申报。Fly-by-wire System is a full-time,full authority flight control system with'electrical and control augmentation'to solve the contradiction between stability and maneuverability and get an ideal integration between stability and maneuverability. Application of the redundancy technology is an effective way to improve the reliability and fault tolerance of the system. Based on a type of aircraft's Quad-Redundant FBW,this paper described the redundancy management strategy in detail,which is to maximize the utilization of system resources,and to do fault diagnosis,reconfiguration,isolation,and to report accurately.
