Preservation of controllability in linear time-invariant perturbed systems†

Abstract

Preservation of controllability in linear time-invariant perturbed systems'] J. H. CHOW:\:The controllability of systems with weak connections is studied. A necessary and sufficient condition for a singularly perturbed system to be strongly controllable is obtained. The controllability invariance of the slow subsystem of a singularly perturbed system due to a. class of fast feedback controls is shown.
