摘　　要：传统的集中式飞控系统构架,与机电、任务等其他系统相互独立,难以满足现代战斗机系统综合设计的要求,而具备开放性和综合控制特征的分布式系统构架是技术发展的必然趋势。基于分布式系统架构的飞控系统容错设计展开研究,首先,介绍分布式飞控系统的典型系统架构及其容错设计的目标;其次,针对分布式系统的运行时序特点,开展基于时间的容错设计;最后,针对分布式系统的组成和体系构架特点,设计多级表决/监控面。通过对分布式系统的运行时序、组成和体系构架特征的分析,梳理分布式系统容错设计的关键切入点,阐述容错设计方案的解决思路和实施方式。经工程实践验证,结果表明:本文所研究的容错设计技术可保证飞控系统运行稳定可靠,有效提升了系统安全性。The traditional centralized flight control system architecture is independent of other systems such as electromechanical and mission systems,making it difficult to meet the requirements of modern fighter system comprehensive design.The distributed system architecture with openness and comprehensive control features is an inevitable trend in technological development.In this paper,the fault-tolerant design for flight control systems based on distributed system architecture is studied.Firstly,the typical system architecture of distributed flight control systems and the objectives of their fault-tolerant design are introduced.Secondly,based on the operational timing and working mode characteristics of the distributed system,a time-based fault-tolerant design is conducted.Finally,based on the composition and system architecture characteristics of the distributed system,a multi-level voting/monitoring surface is designed.By analyzing the running time sequence,composition and architecture characteristics of distributed system,the key entry points of fault-tolerant design of distributed system are sorted out,and the solutions and implementation methods of fault-tolerant design scheme are expounded.The engineering practice shows that the fault-tolerant design scheme studied in this paper can ensure the stable and reliable operation of flight control system and effectively improve the system security.
