CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishThis paper solves the problem to detect and isolate faults in linear periodic discrete-time systems. A residual generator is designed through a suitable unknown input observer with the requirement that each residual should be sensitive only to one fault and, simultaneously, insensitive to the other faults that can affect the system, and with the additional requirement of -detectability, that is the transition matrix of its relative error system has all eigenvalues smaller than , in modulus, for a given positive 1. The solution is based on geometric tools, and it makes use of the outer observable subspace notion.

| Abstract: | This paper solves the problem to detect and isolate faults in linear periodic discrete-time systems. A residual generator is designed through a suitable unknown input observer with the requirement that each residual should be sensitive only to one fault and, simultaneously, insensitive to the other faults that can affect the system, and with the additional requirement of -detectability, that is the transition matrix of its relative error system has all eigenvalues smaller than , in modulus, for a given positive 1. The solution is based on geometric tools, and it makes use of the outer observable subspace notion. |
