多重BP神经网络分流结构在控制系统故障诊断中的应用

A Dividing Structure of Multi-BP Neural Networks Applied in Fault Diagnosis of Control System

提出了多重ＢＰ（ＢａｃｋＰｒｏｐａｇａｔｉｏｎ）神经网络分流结构，以减少ＢＰ算法的学习时间，提高故障模式识别率。把这种方法应用于控制系统的故障诊断，实验结果证明，该方法可行，收到满意效果。

A dividing structure of multi-BP neural networks was presented,which could decrease the learning time of BP algorithm and promote the recognizing rate of fauIt mod-els.The experimental results showed that it was feasible and satisfied for the method beingused in fault diagnosis of control svstem.
