Synchronization Control for a Class of Discrete-time Chaotic Systems with Uncertainty

研究了一类含不确定项的离散混沌系统的同步控制.通过构造动态补偿器,给出了一个新的同步控制器设计方法,从而有效地抑制了不确定项的影响.由于不使用Lyapunov函数,避开了复杂的求导和放大运算,计算简单.该方法也可以用来解决其他类型的混沌系统的同步问题.最后,用仿真算例验证了所给方法的有效性。

In this paper,the synchronization control for a class of discrete-time chaotic systems with uncertainties is discussed. By constructing dynamic compensator,a new synchronization controller is proposed,and the effect of uncertainties is inhibited success-fully. Due to the useless of Lyapunov function,the complex derivation and enlarge computing are avoided,and computing is simple. The proposed method can be applied to solving the synchronization of any other discrete-time chaotic systems. Finally,numerical simulations are provided to verify the effectiveness and feasibility of the proposed method.
