In this paper, we consider the functional differential equation with impulsive perturbations {x′(t) = f(t, xt), t≥ t0, t ≠ tk, x ∈ ℝn, Δx(t) = Ik,(t,x(t-)), t = tk, k ∈ ℤ+. Criteria on uniform asymptotic stability of sets are established for the above system using Lyapunov functions and the Razumikhin technique. Some examples are also discussed to illustrate the theorems. © 2011 Springer Science+Business Media, Inc.
