This paper studies the algebraic structure of linear systems defined over R[λ], the ring of polynomials in λ with real coefficients. Natural definitions of controllability and observability are introduced and properties of R[λ]-transfer matrix realizations are discussed. It is shown that (An×n,Dn×m) is a controllable R[λ]-matrix pair if and only if for each set of polynomialsβ1,β2,…,βn, in R[λ] there exists an R[λ] feedback matrixFsuch that detsI−A−BF]=∏i=1n(s+βi). By regarding λ as a suitably defined delay operator, it is explained how this result might be applied to delay-differential systems in order to control dynamic response.
