Chaos synchronization in autonomous chaotic system via hybrid feedback control

This paper presents the synchronization of chaos by designing united controller. First, this method is implemented in synchronization of a simple system, then we realize the synchronization of Lu¨ hyperchaotic system, we also take tracking control to realize the synchronization of Lu¨ hyperchaotic system. Comparing with results, we can find that hybrid feedback control approach is more effective than tracking control for hyperchaotic system. Numerical simulations show the united synchronization method works well.
