摘要
随着航空发动机控制技术的发展,全权限数字电子控制(FADEC)系统的可靠性设计变得越来越重要;面对目前国内关于航空发动机高可靠性FADEC软件系统研究工作相对滞后的现状,针对硬件层基于相似余度技术,软件层基于非相似余度技术构成高可靠性FADEC系统的相关软件技术进行了研究;在提出FADEC系统软件非相似技术容错结构设计方案后,论文就此容错结构设计方案中的主要技术问题进行了研究。
With the development of aeroengine control technology, reliability of Full Authority Digital Electronic Control (FADEC) becomes more and more important. So, in the design of highly reliable FADEC system, it is greatly necessary to enhance research & development of fault-tolerant software system. Software technique applied to highly reliable FADEC system is studied. The FADEC system consists of hardware layer based on similarity redundancy technique and software layer based on dissimilarity redundancy technique.
