Reachability, observability and minimality for a class of 2D continuous-discrete systems

Valeriu Prepeliţă, Ionel Ţevy

Abstract

Reachability and observability criteria are obtained for 2D continuous-discrete time-variable Attasi type systems by using suitable 2D reachability and observability Gramians. Necessary and sufficient conditions of reachability and observability are derived for time-invariant systems. The duality between the two concepts is emphasized as well as their connection with the minimality of these systems.
