摘要:
针对一类具有不确定项的时滞混沌系统的同步问题,提出了自适应控制策略.基于Lyapunov-Krasovskii函数方法和泛函微分方程的稳定性原理,设计了控制器和自适应律,实现了具有不确定项的时滞混沌系统的同步控制.该控制策略中不合有时滞项,不仅适用于时滞时间已知的时滞混沌系统,而且适用于时滞时间未知以及多时滞的混沌系统.所设计的控制器简单、易于实现,且无需事先已知不确定项的上界,具有较强的实用性和鲁棒性,通过引入同步加速因子,可以任意配置同步速度.通过数值仿真,验证了所提方案的有效性.
Abstract:
This paper primarily investigates the adaptive synchronization of a class of time-delay chaotic sys-tems with uncertainties. According to Lyapunov-Krasovskii functional and the Lyapunov stability theory,thecontroller and adaptive law are designed. The control strategy does not contain time-delay terms,which can beapplied to time-delay or multiple time-delay chaotic system,whoes time-delay is known or unknown.The ap-proach is more robust to noise and external interference,and does not need to known the upper bound of un-certainties in advance. In addition,it can adjust the system response rapidly by adjusting the accelerated fac-tor. Numerical simulations verify the effectiveness of the proposed method.
