灰色关联故障诊断方法在模拟电路中的应用研究

本文介绍了灰色关联故障诊断法的概念、特点，并以笔者近期所参与的项目研究工作中涉及的某装备模拟电路的故障诊断为例，详细介绍了灰色关联故障诊断方法在模拟电路故障诊断中的应用。文中给出了参数选择方法、状态矩阵建立过程、关联度计算公式以及实际应用中的计算步骤，通过计算实现了故障诊断与定位，从而得出了这种方法可较好的用于模拟电路故障诊断的结论。

Study for the application of the gray association fault diagnosis in simulation circuit

This paper introduced the concept and characteristic of the gray association fautt diagnosis.It chose an example of a simulation circuit in in a kind of equipment and introduced the application the gray-associatlon fault diagnosis in siraulation circuit in detail.The paper gave the method of the preferences selecting, the foundation process of the state matrix,the calculstion formula and approach of the gray association. Thus this method realizes fault diagnosis and orientation.
