摘要: 將滑?？刂撇呗杂糜跁r延混沌系統(tǒng)的同步，采用了對系統(tǒng)參數(shù)攝動魯棒性好的變結(jié)構(gòu)控制，使系統(tǒng)對噪聲和參數(shù)失配情況具有更強的魯棒性。同時將自適應(yīng)技術(shù)、系統(tǒng)辨識技術(shù)應(yīng)用于系統(tǒng)中的未知參數(shù)逐步逼近，實現(xiàn)具有擾動以及參數(shù)未知的時延混沌系統(tǒng)的同步。仿真結(jié)果證實了該方法的有效性。

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. -
