在BP型ANN网络用于模拟电路故障诊断的基础上,提出了利用GA辅助设计的BP型ANN实现模拟电路故障诊断的新方法。实例验证表明,新方法的诊断精度、诊断速度以及建立诊断模型的自动化程度都有了较大的提高。 Based on BP artificial neural network used for fault diagnosis of analog circuits, a new method of fault diagnosis for analog circuits based on BP artificial neural network (ANN) is proposed. The example verification shows that the diagnostic accuracy, diagnostic speed and the degree of automation of establishing the diagnostic model have been greatly improved.
