The purpose of this paper is to examine the problem of controlling a linear discrete‐time system subject to input saturation in order to have its output track (or reject) a family of reference (or disturbance) signals produced by some external generator. It is shown that a semi‐global framework, rather than a global framework, for this problem is a natural one. Within this framework, a set of solvability conditions are given and feedback laws which solve the problem are constructed. The theory developed in this paper parallels the one we developed earlier for the continuous‐time system. © 1997 by John Wiley & Sons, Ltd.
