Fault Diagnosis of Single sub-network for Black-box
Youchun Zhang · Journal of Circuits and Systems · 2000
“black box” sub-network fault diagnosis means a kind of diagnosis only based on the Volt-Ampere characteristic derived from the outside terminals of the sub-network concerned. To do this, it is not necessary to know the internal structure and parameters. In this paper , “orthogonal projection method” is developed for the fault diagnosis of single-subnetwork. Using this method, the fault can be located by testing the sub-network in question only once, and without the problem of error propagation. Therefore, the proposed method has theoretical and practical significance for multi-terminal integrated circuit fault diagnosis.
