Abstract
The invention relates to a chaotic system synchronization method and circuit, in particular to an adaptive synchronization method and circuit of a memristor-based x-power-including Chen hyper-chaotic system. As a physical element being newly discovered by the HP Labs in 2008, a memristor can construct a chaotic system instead of a Chua's diode in a Chua's circuit, and can be added into a three-dimensional chaotic system such as a Lorenz system, a Chen system and a Lorenz system as an element, thereby forming a hyper-chaotic system. At present, a method and a circuit for forming chaos or hyper-chaos by taking the memristor as an element are already put forward. However, a synchronization method for forming the hyper-chaos system by taking the memristor as an element is not put forward yet, which is a defect in the prior art. The invention provides the x-power-including Chen hyper-chaotic system by using the memristor, and provides the adaptive synchronization method of the chaotic system on the basis.
