This manuscript presents a controller design method for regional pole placement of uncertain discrete-time systems. The design takes into consideration the control signal limits imposed in practice. A sufficient condition is derived for the robust stabilization and the desired dynamic performance represented by the settling time and damping ratio. Linear matrix inequality (LMI) optimization is used as a design tool. Two examples demonstrate the effectiveness of the proposed design. The first one is hard disk drives, whose uncertainty is modeled by a norm-bounded form. The resulting controller does not violate the limits, and the second example is on regional pole placement for an uncertain system with and without control saturation.
