    The geometry of the set of generalized partial realizations of a finite nice sequence of matrices is studied. It is proved that this set is a stratified manifold, the dimension of their strata is computed and its connection ...
  • On the geometry of the solutions of the cover problem 

    Puerta Sales, Ferran; Puerta Coll, Xavier; Zaballa, Ion (2003)
    Article
    Open Access
    For a given system (A;B) and a subspace S, the Cover Problem consits of ¯nding all (A;B)-invariant subspaces containing S. For controllable systems, the set of these subspaces can be suitably strati¯ed. In this paper, ...
  • On the parametrization of the controllability pairs of a controllable subspaces of a controllable pair 

    Puerta Sales, Ferran; Puerta Coll, Xavier; Zaballa, Ion (2004)
    Article
    Open Access
    Given a controllable linear control system defined by a pair of constant matrices (A,B), the set of controllability subspaces is a stratified submanifold of the set of (A,B)-invariant subspaces. We parametrize each strata ...

  • Output Maximal Dimension for the Disturbance Decoupling Problem 

    Puerta Sales, Ferran; Puerta Coll, Xavier; Zaballa, Ion (2001)
    Article
    Open Access
    Given a linear time invariant system with a disturbance we describe a method of finding the maximal dimensional output for a generic Disturbance Decoupling problem.
