本文给出了从系统的测试响应求故障的新方法,适用于任意故障模型;提出了在系统诊断中采用自适应测试的思想。自适应测试将使自诊断系统的测试次数大大减少,从而可节省时间。自适应测试不仅适用于任意故障模型,而且一步t可测和顺序t可测均可采用自适应测试。本文给出的求自适应诊断树的算法对故障矩阵而言是多项式复杂性的。 In this paper, a new method to find fault from system test response is given, which is suitable for any fault model. The idea of ​​using adaptive test in system diagnosis is proposed. Adaptive testing will save you time by greatly reducing the number of tests you have to make in a self-diagnostics system. Adaptive testing is not only applicable to any failure model, but one step t can measure and order t can be measured using adaptive testing. The algorithm for finding an adaptive diagnostic tree presented in this paper is polynomial complexity for fault matrices.
