Abstract :
In this paper we address the problem of detecting and isolating faults from noisy input/output measurements of a MIMO uncertain-system. The main result of the paper shows that using Caratheodory-Fejer´s theorem to reduce it to an LMI feasibility problem can solve this problem. These results are illustrated with a simple example.
