On Matrices Arising In Retarded Delay Differential Systems



Authors : S. Djezzar S .

Abstract

In this paper, we consider a class of differential systems known as retarded delay differential systems and to which we associate a system matrix over R[s,z], the ring of polynomials of two indeterminates s and z. Then using the notion of Smith form matrix over R[s,z], we extend a previously obtained characterization results [5], on canonical forms, to a more general case

Keywords

Linear systems, retarded delay differential systems, controllability, system matrices, canonical forms
