Robust Stabilization of Chaos via Delayed Feedback Control

Delayed feedback control (DFC) is a useful method of stabilizing unstable fixed points of chaotic systems without their exact information. In this paper, we present a new recursive method for DFC, which enables us to easily design robust DFC. Since this recursive DFC is essentially dynamic feedback, it can overcome the so-called odd number limitation. Hence, it can robustly stabilize almost all unstable fixed points of chaotic systems.
