A backstepping procedure is proposed for disturbance-free discrete-time systems. The feedback law designed by using backstepping coincides with the predictor-based feedback law used in continuous-time systems with input delays. However, simple examples demonstrate that the sensitivity of the closed-loop system with respect to modeling errors increases as the value of the delay increases. The paper proposes a Lyapunov redesign procedure which can minimize the effect of the uncertainty.
