| Chaotic phenomenon is widely in our reality, In recent years with the development of the chaos synchronization, and penetrates into many fields of science, make chaos synchronization with very large study of practical significance.This paper firstly summary introduces the concept of chaos synchronization, and summarizes the several typical chaotic synchronization method. Judge synchronization is given lyapunov index method and lyapunov function method; And lyapunov function method in the chaotic system based on the research of generalized synchronization and complex network synchronization.In the field of generalized synchronization, introduces the current research status of generalized synchronization, taking the classical chaotic system for example, Lorenz. Respectively,Lorenz chaotic system were studied with the structure of the generalized synchronization, Lorenz system and the vision of Liu system structure of the generalized synchronization were studied.Design the corresponding controller. Through the Matlab software simulation, verified by doing the correctness of the generalized synchronous theory with universal. In the complex network synchronization, research network synchronization of chain;Through constructing peculiar lyapunov function, designed a kind of controller. Add in the end of the chain network nodes,to achieve the chaos synchronization between the entire network node. Lorenz system and for network node, take the number of three nodes simulation, proves the validity of this method. |
