基于模糊模式识别的模拟电路故障诊断方法

Analog circuit fault diagnosis method based on fuzzy pattern recognition

针对模拟电路特征参数与工作模式之间关系具有模糊性,采用模糊模式识别方法,通过分析电路故障模式与电路特征参数的模糊映射关系,建立电路故障模糊集字典,是实现模拟电路的故障诊断的方法之一。

Due to the fact that the relationship between the characteristic parameter of the circuit and working mode is fuzzy, this paper uses fuzzy pattern recognition, through the analysis of the fuzzy mapping between circuit fault pattern and circuit characteristic parameter, to establish the fuzzy set dictionary of circuit fault, so as to realize the fault analysis of analog circuit.
