Robust FDI with mixed H<inf>2</inf>/H<inf>∞</inf> criteria for discrete-time linear systems

Abstract:

in this work, the problem of robust fault detection in discrete time uncertain linear systems is studied. The robustness is analyzed using the characterization of two types of perturbation signals: energy signals and bounded power signals. For these two types of signals, H2/H ∞ mixed performance approaches are used for fault detection filter design. The robust filter synthesis is obtained generating a convex optimization problem, whose numeric solution is reached by means of linear matrix inequalities (LMI). The approach is a simple procedure for the design of robust fault detection filter. Copyright © 2005 IFAC.
