Computation of structural invariants of generalized state-space systems
In this paper, we develop an algorithm for computing the zeros of a generalized state space model described by the matrix 5-tuple (E; A;B;C;D), where E may be a singular matrix but det(A ? E) 6 = 0. The characterization of these zeros is based on the system matrix of the corresponding 5-tuple. Both the characterization and the computational algorithm are extensions of equivalent results for sta...
متن کاملComputation of irreducible generalized state-space realizations
In this paper, an efficient, numerically stable procedure is presented for the computation of irreducible generalized state-space realizations from non-minimal ones. The order reduction is performed by removing successively the uncontrollable and the unobservable parts of the system. Each reduction is accomplished by the same basic algorithm which deflates the uncontrollable part of the system ...
متن کاملStability margins for generalized state space systems
In this work we extend results from the literature on H∞ design with pole placement constraints to the case of generalized state space models, for both continuous-time and discrete-time systems. We also propose tests using linear matrix inequalities of reduced dimension. © 2005 Elsevier Ltd. All rights reserved.
متن کاملOn the Stability Radius of Generalized State-space Systems
The concept of \distance to instability" of a system matrix is generalized to system pencils which arise in descriptor (semi-state) systems. Diiculties arise in the case of singular systems, because the pencil can be made unstable by an innnitesimal perturbation. It is necessary to measure the distance subject to restricted, or structured, perturbations. In this paper a suitable measure for the...
