In this paper an important problem in chaos control theory concerning the possibility of generating a new stable periodic solution by a small feedback control law for a dynamical system is addressed. It is proved that a solution with an initial point being some kind of non-wandering property can become a new asymptotically stable solution by a small feedback control law. This shows that the popular opinion that a small control law is not able to create a new periodic point is untrue, and suggests a new approach to controlling chaos.
Keywords: chaotic systems; non-wandering point; small control law.
