Fault Diagnosis Algorithm Based on Multilevel Flow Model for Flow Process

通过一个简单的流过程介绍了采用多级流模型技术进行系统建模和利用其模型进行故障定位诊断的原理。提出了通过矩阵运算实现故障搜索的方法,并提出了传播路径状态矩阵状态向量、节点影子状态矩阵等新定义,将有利于发挥多级流模型在快速故障诊断中的高效率。

A simple flow process has been modeled which used Multilevel Flow Models technique,and the model can be used for fault diagnosis.A method of fault search by the matrix operation,and the state vector of transmit path state matrix,and a shadow state matrix and others new node definition has been proposed.It will make the best use of high efficient of the Multilevel Flow Models in fast fault diagnosis.
