摘要
研究了驱动系统为参数未知的离散混沌系统时的同步问题,通过设计响应系统中的参数与控制器,实现驱动-响应系统的同步,识别出驱动系统的未知参数。基于离散系统的Lyapunov稳定性定理,给出了理论推导。以离散Hénon混沌系统为例进行了数值仿真,验证了该方法的有效性。
This paper studies the problem of synchronization when the driving system is a discrete chaotic system with unknown parameters.By designing the parameters and controller in the response system, the synchronization in the driving-response systems is achieved.Moreover,the unknown parameters in the driving system are identified.Based on the Lyapunov sta- bility theorem of the discrete system, theoretical result is proposed.In addition, the discrete H6non map is taken for iUustration and verification.
