Abstract: | The problem of finite-time combination synchronization for a class of complex-variable chaotic systems was investigated. Firstly, for the synchronization mode in signal transmission, the multi-switching synchronization behavior among multiple chaotic systems was analyzed. Secondly, based on the preset switching rules, the definition of finite-time combination synchronization was given. Then, according to the theory of finite-time stability, a kind of controller was designed to realize fast synchronization, and the sufficient conditions were given. Finally, results of numerical simulation and analysis verify the effectiveness of the proposed control scheme. |
