摘　　要：提出了一种可以评价模拟电路工作状态的故障度量化算法.因为模拟电路里存在一些模糊量,本文将模拟电路视为模糊系统.提出了基于模糊隶属函数的故障度量化函数,并与决策函数相结合构成了模拟电路故障度量化算法.对模拟电路的故障程度进行精确量化,有助于模拟电路故障诊断和故障修复.故障度量化算法可以计算模拟电路的全局故障度,从而准确地、客观地评价模拟电路的故障水平.A quantifying algorithm of fault-degree is proposed to evaluate the working state of analog circuits. Because there are a lot of fuzzy physical quantities in analog circuits, analog circuits are regarded as a fuzzy system. The fault-degree quantifying functions are proposed based on fuzzy membership functions. These functions and the decision function are combined to constitute the quantifying algorithm for determining the fault-degree in analog circuits. Accurately quantifying the fault-degree is helpful to fault diagnosis and fault recovery of analog circuits. The fault level of analog circuits can be evaluated by the global fault-degree accurately and objectively.
