基于时滞输出反馈的鲁棒混沌同步控制

Robust output feedback synchronization on uncertain chaotic systems

研究了一类含有不确定参数和时滞的混沌系统的鲁棒同步控制问题。构造一个增广型Lyapunov泛函,并结合同步控制理论,提出了一种能够消弱不确定扰动项的输出反馈控制器设计方法。在该控制器的控制下,可使从系统的状态全局同步于主系统的状态。仿真实例说明了所设计的控制器的有效性。

The robust synchronization problem of a class of chaotic systems with uncertain parameters and time-varying delay was investigated. Based on augmented Lyapunov functional and synchronization theory, a novel robust output feedback controller was proposed. The proposed controller can be successfully applied to reduce the effect of uncertain disturbance. Simulation results verify the effectiveness of the proposed controllers.
