Synchronization hyperchaos of hyperchaotic systems

This work presents hyperchaos synchronization of two identical hyperchaotic systems and of two different hyperchaotic systems by using active control. This technique is applied to achieve hyperchaos synchronization for hyperchaotic Lü system and for hyperchaotic Chen system, also, is applied to achieve hyperchaos synchronization between hyperchaotic Lü system and hyperchaotic Chen system. Numerical simulations are shown to verify the results.
