| 摘 要： | 为了验证奇异值分解法（SVD）存冗余惯性组件系统故障诊断中的实用性，进行了一系列的研究。以沿正十二面体对称侧面配置的六陀螺冗余惯件组件为平台，对2种基于奇异值分解的故障诊断方法进行了相心的实验，分析了不同类型故障下的故障诊断效果及其原因。实验结果证明了方法在实际应用中的有效性，2种疗法均可以正确的诊断出故障。奇异值分解法中的方法2不仅可以检测一个陀螺的故障，还可以检测2个陀螺同时发生故障的情况，有更广泛的实用价值。

| Abstract: | The single valued decomposed(SVD) method applied in FDI of redundant inertial navigation system was mainly researched.2 FDI methods were discussed based on SVD;in which 2~(nd) method can detect the situation of 2 faults occur simultaneously.Based on the six-gyroscope redundant inertial measurement unit,different performances of these methods were evaluated;the possible causes which affect their fault detection capability were analyzed.The result proves that the SVD method is effective in practice. |
