Résumé:
This work presents Auto-FDI (Automatic Fault Detection and Isolation), a software
tool for detection and diagnosis of faults in systems. The tool uses the analytical
redundancy concept, where signals from the (possibly faulty) system are compared with
expected signals from a model. The fault isolation employs a technique developed on
this work, called automatic isolation. This technique uses a graph-based approach
which considers the fault propagation and the lack of information about certain
components of the system. Faults are pinpointed as accurately as possible given the
level of detail in the model. In the scope of this work was addressed the whole process
of specification, design, implementation and validation of the tool - used as proof of
concept for the developed technique. The validation of the tool was made by conducting
a case study for potential users, that has demonstrated the applicability of the tool and
the technique developed.
