| 摘 要： | 从联邦滤波的故障检测特点出发,以SINS/GPS/ADS/TACAN/RADAR组合导航系统为对象,对基于量测一致性和残差χ2检测的两级故障检测法、双状态递推故障检测法两种系统级故障检测方案进行了较为详细的分析比较,并通过预设故障模型进行了仿真.仿真结果表明:故障检测部分的加入可有效地提高多传感器组合导航系统的容错性和可靠性.两种检测方案对软、硬故障都有较高的灵敏度,但都不同程度出现误警和漏检情况,总体而言,基于量测一致性和残差χ2检测的检测方案更有优势.

| Abstract: | Base on the characteristics of federated filtering structure,comparison and analysis are made between two schemes for system-level fault diagnosis in the SINS/GPS/ADS/TANCAN/RADAR integrated navigation.The two schemes are: 1) a two-stage fault detection technique based on measurement consistent and the Chi-square test;and 2) a dual-state recursive fault detection method.Simulation is made through faults setting.The result showed that the fault detection approaches are effective to improve the fault-toleranc... |
