| 摘 要： | 传统的故障诊断模糊综合决策法存在着３个不足：只由某一（而不是所有）征候决定诊断结果；权值的归一化引起由权值（而不是故障征侯）决定诊断结果：一种征候对所有故障取相同权值。给出改进的故障诊断模糊综合决策法模型，修正以上不足。将其用于液压泵２故障诊断综合决策法模型，修正以上不足。将其用于 泵故障诊断，得到正确的诊断结果，证明新模型的可靠性。

| Abstract: | General fuzzy decision for fault diagnosis has its shortcomings: (1)the diagnosis result is decided by one symptom, (2)the diagnosis result is decided by the weight, (3)the same weights to different faults are selected for one symptom . The improving method and model are put forward in this paper. The new model corrects the shortcomings as above. Applying the model to the fault diagnosis for hydraulic pumps, satisfying results are acquired, and the reliability of the model is testified. |
