| Abstract: | This paper introduced a new method to diagnose circuits, that is, multiplayer artificial neural network of layer structure and screening out the training samples by the expert knowledge. It overcame the drawback of the circuit fault diagnosis of a certain missile director in the expert system. The experiment results on the difference circuit module in the system showed that the new method can overcome some faults that expert system cannot diagnose and realize the diagnosis on the multiple faults. |
