a Method for the Synchronization of Hyperchaotic Circuits

In this paper the Carroll–Pecora concept of chaotic system synchronization is extended to the synchronization of hyperchaotic circuits. A circuit exhibiting a hyperchaotic behavior is duplicated to generate two cascaded response subsystems, properly driven by synchronizing signals. Conditions for achieving synchronization are illustrated in detail. The proposed method is applied to two identical unidirectionally coupled hyperchaotic Chua’s circuits.
