一类参数不确定超混沌系统的反同步

Anti-synchronization of a Class of Hyperchaotic System with Uncertain Parameters

利用自适应控制理论,设计控制器和参数自适应控制律,实现了一类参数不确定的异结构超混沌系统的反同步,并用稳定性理论证明了该方法的有效性,同时对具体的超混沌Chen系统和超混沌Rssler系统进行反同步仿真,结果证明数值计算与理论分析一致.

Adaptive anti-synchronization method is different structure, and the numerical simulation presented to study a class of hyperchaotic systems with of hyperchaotic Chen system and hyperchaotic Roessler system is given. The adaptive controller is designed for synchronizing response system and drive system. When the parameters are fully unknown, the analytical expression of anti-synchronization controller and adaptive law of parameters is given based on adaptive control and Lyapunov stability theory, which makes the different systems reach to anti-synchronization and identifies the unknown parameters. Numerical simulation shows the effectiveness and feasibility of the method.
