  • H2 optimal robust filtering
    José C. Geromel, UNICAMP (Campinas, Brasile)
    mercoledì 7 luglio 2004 alle ore 17:00, Dipartimento di Matematica - Università degli Studi di Milano - Via Saldini 50 - Milano - Sala di Rappresentanza
    In this seminar, a new design procedure for H2 optimal robust filtering is presented. The robust filter is determined from the equilibrium solution of a minimax programming problem where the H2 norm of the estimation error is maximized with respect to the feasible uncertainties and minimized with respect to all full order, linear, rational and causal filters. It is shown that for the class of parameter uncertainty considered, the equilibrium solution of the aforementioned minimax problem can be exactly determined. In contrast to the design methods available in the literature to date, the proposed one does not include any degree of conservatism. The classical static linear approximation problem as well as the filter design problem corresponding to continuous and discrete time linear systems are considered. An illustrative example is presented. The seminar ends with a discussion on a problem still unsolved.

    Anti-reflecting boundary conditions (AR-BC) for blurring models
    were recently introduced (see Serra-Capizzano, SISC, 2003):
    the idea seems promising both from the
    computational and approximation viewpoint. The key point is that,
    under certain symmetry conditions, the AR-BC matrices can be
    essentially simultaneously diagonalized by the (fast) sine transform
    DST I and, moreover, a greater regularity at the border is guaranteed.
    We present a technique for combining AR-BC, regularization processes
    which are unavoidable when the noise is introduced, and linear algebra
    solvers defined ad hoc for the considered structures.
    Extensive numerical simulations which illustrate that the AR-BC can be
    superior to Dirichlet, periodic and reflective BCs in certain
