摘要:
针对一类具有未知时变参数与时滞的混沌系统，提出一种自适应间歇控制策略以解决其指数同步问题。为此，设计了时滞适配的自适应间歇控制器与参数更新律，实现同步处理时滞与未知时变参数，并放宽了“控制宽度须大于时滞上界”的严格限制。本文基于Lyapunov 稳定性理论与微分不等式，严格推导了误差系统实现全局指数同步的充分条件，并通过数值仿真验证了所提控制方案的有效性。
Abstract:
This paper addresses the exponential synchronization problem for a class of chaotic systems with unknown time-varying parameters and time delays by proposing an adaptive intermittent control strategy.To this end,a delay-matched adaptive intermittent controller and parameter update laws are designed,enabling the simultaneous handling of time delays and unknown time-varying parameters while relaxing the stringent restriction that the control width must exceed the upper bound of the time delay.Based on the Lyapunov stability theory and differential inequalities,sufficient conditions for the global exponential synchronization of the error system are rigorously derived.Numerical simulation results demonstrate the effectiveness of the proposed control scheme.
