The present invention relates to a chaotic system synchronization method and a circuit, particularly to an adaptive synchronization method and adaptive synchronization circuit of y<2>-contained Chen hyper-chaotic system based on memristor. The memristor, served as a new physical component found by the HP labs in 2008, may take the place of the Chua's diode in the Chua's circuit to form the chaotic system, and also may be a component to be added into the three-dimensional chaotic systems, such as a Lorenz system, a Chen system and a Lorenz system, in order to form the hyper-chaotic system At present, the method and the circuit of serving the memristor as a component to form the choas or the hyper choas have come up, but the synchronization method of serving the memristor as a component to form the hyper-chaotic system has not yet come up, so that there is provided an inadequacy in the prior art. According to the invention, the y<2>-contained Chen hyper-chaotic system based on the memristor is put forward, and on this basis the adaptive synchronization method of y<2>-contained Chen hyper-chaotic system is provided.
