Bounding approach to the diagnosis of uncertain static systems

Résumé

A novel approach to the diagnosis of uncertain static systems is described. Using this approach, a diagnostic procedure can take some uncertainties into account at the time of a decision, instead of dismissing them, as is often the case. After first itemizing the basic principles and then formulating the diagnostic problem in an uncertain context, a method based on an analysis of parallelotopes representative of the uncertainties in question is described. The presentation of this approach is the major theoretical part of this work. The authors subsequently explain how to determine an indicator representing the difference between the real behavior of the system and the limit of its normal behavior. This approach is compared with a traditional parity space approach in order to highlight the fact that the bounding approach offers guarantees that other approaches cannot offer.
