Abstract: The design of observers for a class of discrete chaotic systems is discussed.Only using a state variable and its time delays,one can construct a control law to implement the synchronization between the investigated chaotic systems and their observers.Simulation results on several well-known chaotic systems show the usefulness of the suggested method.

Key words: chaotic systems, observers, synchronization
