摘　　要：为了解决电器控制系统故障定位的模糊性和不确定性问题,在综合考虑了引起故障的主要因素后,采用层次分析法,实现对故障的定量评估和定位决策。依照功能、设备、元件的层次结构,由上而下进行功能分解;在定位决策过程中,将基于静态知识的专家经验和基于动态测试的定量计算相结合,最后给出了对航空电器控制系统中继电器故障定位的具体实现过程。该方法可以适应不同电器控制系统的故障定位,对故障诊断策略实现起到指导作用。In order to solve fuzzificaiton and uncertainty of electrical apparatus control system fault location, analytic hierarchy process-based （AHP） method is adopted to achieve decision of fault location and quantitative estimation when multi factors are taken into consideration. The hierarchical structure is decomposed from top to bottom according to system function, element relationship and component structure. Static expert knowledge is combined with dynamic computing process. As an example, fault location realization of aerospace electrical apparatus control system is achieved. The method can be applied to different electrical apparatus control system fault location, and it is easy to achieve fast fault diagnosis strategy.
