Abstract
Handling of multiple simultaneous faults is a complex issue in
fault-tolerant control. The design task is particularly made
difficult by to the numerous different cases that need be analyzed.
Aiming at safe fault-handling, this paper shows how structural
analysis can be applied to find the analytical redundancy relations
for all relevant combinations of faults, and can cope with the
complexity and size of a real system. Being essential for
fault-tolerant control schemes that shall handle particular cases of
faults/failures, fault isolation is addressed. The paper introduces
an extension to structural analysis to disclose which faults could
be isolated from a structural point of view using active fault
isolation. Results from application on a marine control system
illustrate the concepts.
