| 摘 要： | 该文改进了基于互测PMC模型的系统级故障诊断集团算法的理论，通过定义集团测试边和绝对故障集，简化了集团诊断图，由此能较易地找到所有的基于互测PMC模型的相容故障模式(即使不满足t—可诊断性)，从而大大减少了系统级故障诊断的复杂度，尤其是对强t—可诊断系统。

| Abstract: | This article improves on the theory of Node Grouping Algorithms in System-level Fault Diagnosis of PMC Model Based on Ex-test. By defining the Group's testing edge and the absolute fault sets, the Group diagnosis chart is simplified ,so all the CFP of PMC model based on ex-test can be easily found even if the condition of the t-diagnosable isn't satisfied. Hence the complexity of system fault diagnosis is greatly decreased, especially in the strong t-diagnosable system. |
