摘要
The aim of this Letter is to show that the injection of small damping signals can suffice to regulate the motion of a chaotic system around less complex attractors, such as equilibrium points and periodic orbits. The proposed feedback controller is composed by a high-pass filter and a saturator, so its implementation is quite simple and can be made on the basis of measured signals. The Duffing and the Chua systems are used to illustrate the performance of the controller. (C) 2003 Elsevier B.V. All rights reserved.
