利用部分变量研究了两个全同时滞超混沌Lü系统的反同步与完全同步共存问题.基于李雅普诺夫稳定性理论，考虑了一种简单的仅含线性输入的同步方案。对于线性反馈和自适应控制方法，也得到了同步的充分条件。研究了参数未知的两个几乎相同的时滞混沌系统之间的AS和CS共存现象。提出了一种单输入控制器，并给出了自适应参数更新律。数值仿真结果表明了该方法的有效性。
This work is devoted to investigating the coexistence of anti-synchronization (AS) and complete synchronization (CS) of two identical delay hyperchaotic Lü systems via partial variables. Based on the Lyapunov stability theory, a simple synchronization scheme only with linear inputs is considered. The sufficient conditions of synchronization are also obtained for both linear feedback and adaptive control approaches. The coexistence of AS and CS between two nearly identical delay chaotic systems with unknown parameters is explored. A single input controller is proposed and the adaptive parameter update laws are developed. Numerical simulation results are presented to demonstrate the effectiveness of the proposed chaos synchronization scheme.
