为提高卫星综合电子系统的可靠性，介绍了一种卫星综合电子系统的FDIR （fault detection，isolation and recovery）设计与实现方法。根据容错理论与方法，从系统容错结构、故障建模、故障测试算法、故障诊断、故障处理恢复等几方面进行了全面描述，重点介绍了卫星综合电子系统的故障检测、故障隔离以及故障重组的工程化实现，实际测试结果表明，卫星综合电子系统发生故障后系统可自动重组，提高了综合电子系统的容错能力，为卫星综合电子系统FDIR设计提供技术思路和参考。

To improve the reliability of satellite avionics,the design and application of FDIR (fault detection,isolation and reco-very)of satellite avionics were analyzed analyzed.The overall scheme of system fault structure and fault modeling,fault testing algorithm,fault diagnosis,fault recovery were analyzed according to the fault-tolerant theory and method.Description of engi-neering for FDIR of satellite avionics was emphasized.Through the actual test,satellite avionics could automatically reconstitute when a failure occured,so that the its fault-tolerant ability was improved.All these could supply technical references for the present FDIR design of satellite avionics.
