针对存在参数摄动、外扰动等不确定因素的时变时滞混沌系统的同步问题,基于Lyapunov-Krasovskii稳定理论,利用线性矩阵不等式技术,提出了H∞参数自适应的混沌同步控制方法,设计的模糊控制器结构简单,且该方法适用于绝大多数变时滞混沌系统的同步控制。仿真结果表明所提出的控制方法是有效的。
The problem of synchronization of chaotic systems with time-varying delays and uncertain parameters was concerned, and an H∞ parameters adaptive control method was proposed via Lyapunov-Krasovskii stabilization theory and linearitymatrix inequality (LMI) technique. The structure of the fuzzy controller is simple, and this method can be used to the most of the synchronous control of chaotic systems. A numerical example demonstrates the effectiveness of the present method.
