Abstract

The invention relates to a chaotic system synchronization method and a circuit, and particularly relates to a memristor-based Chen hyperchaotic system self-adaptive synchronization method and a circuit. As a physical element which is newly discovered in a Hewlett-Packard laboratory in 2008, a Memristor can replace a Chua diode in a Chua circuit to form a chaotic system, and can be used as an element to be added into a three-dimensional chaotic system, such as a Lorenz system, a Chen system and a Lorenz system to form a hyperchaotic system. At present, the fact that the memristor is used as an element to form a chaotic or hyperchaotic method and circuit is proposed, but the fact that the memristor is used as an element to form a hyperchaotic system synchronization method is not proposed. For shortcomings in the prior art, according to the invention, the memristor is used to propose a Chen hyperchaotic system, and the self-adaptive synchronization method of the chaotic system is proposed on the basis.
