研究了存在参数扰动的超混沌系统的自适应同步问题。基于Lyapunov稳定性理论,设计了自适应控制器,从理论上证明了该控制器可以实现存在参数扰动下超混沌Qi系统的自同步,以及超混沌Qi系统和超混沌Lorenze系统间的异结构同步。最后数值仿真实验进一步验证了所提出方案的有效性。
The problem of adaptive synchronization of hyperchaotic systems with perturbed parameters is studied. Based on the Lyapunov stability theory, an adaptive controller is designed. It is proved theoretically that the controller can realize the self-synchronization of hyperchaotic Qi system and the different-structure synchronization between hyperchaotic Qi system and hyperchaotic Lorenze system . Finally, the numerical simulation further verifies the effectiveness of the proposed scheme.
