摘要
在航空航天飞行器设计中,随着主动控制技术、随控布局及电传操纵系统的普遍采用,飞行控制系统的地位变得更为重要。系统容错、冗余技术是为飞行控制系统的高可靠性要求而被提出来的。本文就飞行控制系统的三大组成部分(飞控计算机、伺服机构、传感器)中容错、冗余技术应用的一系列关键问题进行了探讨,提出了飞控系统的冗余配置方案,一种解决冗余系统同步问题的新方法、消除系统交联隅合的措施以及冗余系统中各通道间信息传输的方法。容错飞控计算机是本文阐述重点。
With widespread adopting of the Active Control Technique(ACT) and Control Configuration Vehicle(CCV)and Fly-by- wire system, position of Flight ControlSystem(FCS) become even more significant. Fault Tolerant & Redundant Techniques arethe strong means to increase the reliability of the FCS. In this paper,three parts of the FCSwhich are Flight Control Fault Tolerant Computer,Redundant Servoactuator and Sensorhave been explored,the dey techniques have been solved,such as the Redundant Disposition,Synchronism of the Redundant Channels,Decoupling Among the Channels of Redundant System,Data Link and Communication of Channels,etc. Fault Tolerrant Computer ismain point of the research.
