摘　　要：基于backstepping控制方法研究了两个异结构不确定混沌系统之间的同步问题。根据Lyapunov稳定性理论设计了一种识别Genesio混沌系统未知参数的观察器以及同步控制器,使用backstepping方法实现两个异结构不确定混沌系统之间的同步。选取不确定的Genesio系统和Lü系统分别作为驱动系统和响应系统进行数值模拟,从而证明了该观察器与控制器的有效性。The synchronization problem of two different uncertain chaotic systems is studied by using backstepping method. Based on Lyapunov stability theory, the unknown parameter observer of the Genesio chaotic system and synchronization controller is designed. The backstepping method is used to achieve synchronization of two different uncertain chaotic systems. Genesio system and Lu system are used as numerical simulation of the drive system and the response system. The validity of the observer and controller is demonstrated.
