Abstract
Linear nonautonomous discrete single-input systems in K n, where K is a ring with unit, are studied. Total controllability is defined and every totally controllable system is shown to be representable in canonical form (i.e., as an nth-order scalar equation with coefficients in K). Therefore, every totally controllable system is stabilizable in the sense that all solutions vanish for some linear feedback, beginning from a finite instant.
