This paper is aimed at reviewing the ring of retarded quasipolynomial meromorphic
functions (RMS) that was recently introduced as a convenient control design tool for linear …

Linear control systems over commutative rings are a generalization of linear control systems
used in the study of parametric families of linear systems, 1–3 or in the study of convolutional …

Given a system (A, B) over a commutative von Neumann regular ring R, it is proved that
there exist a matrix F and a vector u such that the single-input system (A+ BF, B u) and the …

Many physical systems in science and engineering can be described at time t in terms of an
n-dimensional state vector x (t) and an m-dimensional input vector u (t), governed by an …
