  This work proposes a notion of robust reachability of one set from another
set under constant control. This notion is used to construct a control
strategy, involving sequential set-to-set reachability, which guarantees robust
global stabilization of nonlinear sampled data systems with positive sampling
rate. Sufficient conditions for robust reachability of one set from another
under constant control are also provided. Finally, the proposed method is
illustrated through two examples.
