K故障容差网络的诊断性研究

研究一类容差网络的Ｋ故障诊断问题，建立起容差值为随机变量的故障网络模型，用正交能量法对网络进行故障定位．给出无容差与容差网络Ｋ故障的可诊断条件，分析了诊断性能好坏与故障网络的哪些因素有关，给出它们之间的关系．对于已知网络结构与容差统计特性的系统，可对其Ｋ故障的可诊断度给出一个概率估计

A Study of Diagnosis in K-Fault Network with Tolerancet

In this paper K-fault diagnosis problem of network with tolerance is developed, a K-fault network model with random tolerance is established, the orthogonal energy approach is presented for locating faults. In this paper a diagnosis condition is also given for K-fault network without tolerance or with tolerance. Some factors relative to diagnosis performance are analysed. A formula is provided to estimate the diagnosed probability of a network with known structure and tolerance statistic character.
