A dynamic delayed feedback controller for chaotic discrete-time systems

Delay feedback control (DFC) is a useful control method with a static feedback gain for chaotic systems. However, it is known that DFC can not stabilize any systems with an odd number of real eigenvalues greater than unity. This paper shows that we can overcome this limitation by using dynamic delay feedback. It is also shown that the order of the dynamic delay feedback controller is not necessarily greater than that of the chaotic system.
