Abstract: The synchronization of a class of chaotic systems with unknown parameters is considered. A novel active adaptive control approach is present. The parameters in the drive system can be known and the response system can be controlled to the drive system. As an example, the perturbed Chua’s system is given and a sufficient condition is showed. Simulation results show the effectiveness of the proposed strategy.

Key words: Chaotic control, chaotic synchronization, adaptive control, active control, Chua system.

摘要: 讨论了一类参数未知的混沌系统的同步问题。基于主动控制思想,提出了一种新的主动自适应控制同步的方法,通过主动控制和参数自适应率使得响应系统的状态变量被控制到驱动系统的状态变量,并且未知参数能够很好的得到辨识。以扰动的Chua系统进行了理论分析和证明,给出了同步的充分条件。数值模拟与仿真说明控制同步策略的有效性。
