摘　　要：针对一类存在不确定性或者未知参数的非线性混沌系统,本文提出一种自适应变结构控制器,并应用到Genesio混沌系统的控制和同步问题中,然后将这种控制方法应用到保密通信中。仿真结果表明所提出的控制策略具有鲁棒性并能够成功用于保密通信。An adaptive variable structure controller for a class of nonlinear chaotic systems is proposed in this paper. This controller can be used for the control and synchronization of the chaotic system whose dynamics are subjected to the system＇s disturbance and/or some unknown parameters. The proposed control scheme is then applied to address the control and synchronization problems associated with the Genesio chaotic systems. Moreover, as an application, it is applied to a secure communication system. Simulation results verify the proposed scheme＇s robustness and success in the communication application.
