摘　　要：为了提高组合导航系统对故障的检测能力,提高系统整体的容错性能,论文在设计联邦滤波器的基础上,在系统级层面上研究了故障诊断方法,并通过Matlab仿真进行了比较和分析。仿真结果表明,基于状态χ~2检验法和残差χ~2检验法两者均能有效地检测出系统的故障,但它们在实际应用中均存在一些缺点,可以在此基础上对两种方法改进,进一步提高系统的容错能力。In order to improve the fault detection ability of the integrated navigation system and the fault-tolerant performance of the system as a whole,this paper studies the fault diagnosis method at the system level on the basis of designing the federated fil⁃ter,and compares and analyzes it through Matlab simulation.The simulation results show that both the stateχ2 test method and the residual χ2 test method can effectively detect the fault of the system,but both of them have some shortcomings in practical applica⁃tion.On this basis,the two methods can be improved to further improve the fault tolerance of the system.
