摘要
研究了一类具有未知Lipschitz常数的非自治混沌系统的自适应脉冲同步问题.首先基于Lyapunov稳定性理论、自适应控制理论及脉冲控制理论设计了自适应控制器、脉冲控制器及参数自适应律,然后利用推广的Barbalat引理,理论证明响应系统与驱动系统全局渐近同步,并给出了相应的充分条件.两个数值仿真例子表明本方法的有效性.
This paper investigated the adaptive impulsive synchronization for a class of non-autonomous chaotic systems with unknown Lipschitz constant. Firstly,based on the Lyapunov stability theory,adaptive control theory and impulsive control theory,the adaptive controller,the impulsive controller and the parametric update law were designed respectively. Then,by the generalized Barbalat s lemma,the global asymptotic synchronization between the drive system and the response system was proved,and some corresponding s...
