摘要: 将滑模控制策略用于时延混沌系统的同步，采用了对系统参数摄动鲁棒性好的变结构控制，使系统对噪声和参数失配情况具有更强的鲁棒性。同时将自适应技术、系统辨识技术应用于系统中的未知参数逐步逼近，实现具有扰动以及参数未知的时延混沌系统的同步。仿真结果证实了该方法的有效性。

Abstract: This paper presents a sliding mode control method for synchronizing a class of unknown parameters time-delayed chaotic system. The variable structure control scheme provides robust synchronization even in the presence of unknown disturbance. And adaptive method is used to estimate unknown parameter. Finally, numerical results are used to show the robustness and effectiveness of the proposed control strategy. -
