动态电路故障诊断的可测性研究

本文是关于动态模拟电路故障诊断中测试点选择问题的研究,在作者提出的关于诊断方程的雅可比矩阵的秩几乎处处恒等这一概念的基础上,研究了对动态电路的多频率诊断法的内在关系,给出了若干重要定理来解决测试点选择问题。

A Study on the Testability of Dynamic Circuit Fault Diagnosis

The problem of selecting the testing point of the fault diagnosis of analog dynamic circuit is studied in this paper. Based on the concept of that "the rank of FEJM is almost identical anywhere", established by the authors, the inner relationship of the multifrequency diagnosis method for a dynamic circuit is studied, some important theorems for solving the problem of testing-point selection are also given in the paper.
