Abstract
This paper deals with the problem of controlling discrete-time linear systems with unknown dynamics and a saturation-type constraint on the control input amplitude. We propose a direct adaptive regulator that globally stabilizes any system with one pole at x=1 and all others inside the unit disk. The regulator design is carried out using the pole placement technique. Of particular interest, the input saturation vanishes after a finite transient period
