摘要
为了验证奇异值分解法(SVD)在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性组件为平台,对2种基于奇异值分解的故障诊断方法进行了相应的实验,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种方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。
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.
