Fault diagnosis in analog and mixed mode low testability system
Janusz A. Starzyk, Jun Pang · 2002
This paper describes our views on how to detect faults in low testability analog or mixed mode (analog electro-mechanical) system. A new method is developed to identify a minimum number of faulty parameters in the system with ambiguities. From sensitivity analysis of the system, we can extract solution invariant matrix and identify singular cofactors of this matrix. The approach can be extended to the electro-mechanical systems, which combine electronic circuits with mechanical components.
