摘要: 讨论了导航系统的故障检测问题,提出通过设计对特定导航系统故障敏感的最优鲁棒向量来检测组合导航系统故障,只利用传感器的测量数据,不需要具体的动态模型,并与常用的奇偶检测法进行了比较.最后以3个导航系统的组合为例,仿真结果显示,鲁棒故障诊断的检测故障、隔离故障效果明显提高.

Abstract: The problem of fault detection of a navigation system is discussed and an approach to detect faults of an integrated navigation system is proposed by designing the optimal robust vector sensitive to special navigation system fault in this paper. Only the measurement data of sensors are used, and the real dynamic model needn't be considered. The proposed approach is compared to the usual parity detection method. Finally, an example of an integrated navigation system composed of three uncorrelated navigation systems is given and simulation results show the robust approach has obviously improved the ability of detecting and isolating fault.
