| 摘 要： | 针对柴油机故障诊断中往往出现故障的症状在识别空间重叠这一问题进行了研究，采用Fisher判别分析方法，在识别空间使各类故障自身进行聚类，而不同故障类别间则放大差异，实际运用结果表明，这种方法对比较复杂的难以区分的故障现象有效的。

| Abstract: | When the fault of diesel engine is diagnosed, the phenomena that the faults' symptoms overlap in the identifiable space usually appear. Undoubtedly it has bad effect on identifying the fault rightly. The identification of faults can not be made. In the article, the problem is analyzed with Fisher identification method, making every kind of fault cluster in the identifiable space. The application shows that the method is effective in comparing complicated faults with undistinguishable ones. |
