摘    要：针对系统级故障诊断研究中的测试模型,提出了非齐次线性方程组的方法,把测试模型等价地转化为非齐次线性方程组,从而以简明的方法寻找所有相容故障模式,并进一步推出最优诊断.理论分析和实验结果表明,该方法相对于基于图论的传统方法更加实用,其方程模型更加简洁明了.

Abstract: A non-idempotent linear equations diagnosis method is presented for test model of system-level fault diagnosis, it can turn the test model into a group of equivalence equations, and search all of consistent fault pattern by concise means , and the optimal diagnosis is presented . The method is more useful and effective than the graph method in test model representation, and it is more concise than equation model.
