遗传算法在故障诊断中的应用研究

The Study of Applications of GA in Fault Diagnosis

板级电路故障诊断过程复杂,故障征兆和故障原因之间存在着许多不确定因素,建立精确的故障诊断系统存在着许多困难。针对这种情况,提出了一种基于遗传算法的故障诊断研究方法,并以某型号电路板为例验证了该方法的有效性。

It＇s well-known that the process of the circuit fault diagnosis is complex. There are many uncertain factors between fault symptoms and fault causes, so it＇s difficult to construct the fault diagnosis system with high precision. To cope with the difficulty, this paper presents a method to construct a fault diagnosis system based on genetic algorithm. The effectiveness of this method is proved with an example of a test on a type of circuit.
