Abstract



Necessary and sufficient conditions are established for the relative, absolute controllability and null controllability of the generalized linear delay system and its discrete prototype. The paper presents illuminating examples on previous controllability results by Manitius and Olbrot [7] and carries over the results of Onwuatu [8] and Klamka [4] to delay systems. It generalizes the results of Sebakhy and Bayoumi [11]. An algebraic approach is adopted in most of the proofs; while a manifestation of interest in the utilization of the asymptotic behaviour of solutions of differential equations provides computable criteria for relative null controllability of linear systems.
