This paper deals with the separation principle for a class of nonlinear dynamical systems whose dynamics are in general bounded in time. The resultant observer-based state feedback control guarantee the convergence of solutions toward a small neighborhood of the origin of the state oscillation given that the system is both uniformly controllable and observable. An example in dimentional two is given to illustrate the applicability of our result.
