摘要

PMC模型是一种基于测试的系统级故障模型.针对传统诊断算法的弱点

作者于2003年建立起了PMC模型方程诊断算法的框架.本文的主要工作是:(1)对以往的理论进一步补充完善;(2)给出一个直接求绝对故障基的简便方法;(3)通过引入直和的概念

将高维PMC故障模型分拆成低维模型进行诊断;(4)举例说明方程诊断算法的应用.

Abstract

PMC model is a kind of system-level fault model based on test.To counter the weakness in traditional diagnosis algorithm

we have set up a framework of equation diagnosis algorithm for PMC model in 2003.The chief works in this paper are as follows:(1)The past theorem is further replenished and complemented;(2)A simple and convenient method for directly getting absolute fault base is given;(3)By introducing the concept of direct sum

more dimensions PMC fault models are separated into less dimensions models to diagnosis;(4)Equation diagnosis algorithm’s applications are illustrated by examples.
