A sufficient condition for Lipschitz stability of controlled Invariant subspaces
Peña Carrera, Marta; Puerta Sales, Ferran; Puerta Coll, Xavier (200912)
Article
Restricted access  publisher's policyGiven a pair of matrices (A,B) we study the Lipschitz stability of its controlled invariant subspaces. A sufficient condition is derived from the geometry of the set formed by the quadruples (A,B, F, S) where S is ...
