摘 要: 对复杂网络的研究已成为焦点问题,它涉及到科学界的各个领域。近年来,复杂网络的同步引起了人们的广泛兴趣。时间延迟反馈法就是一种比较常见的同步方法,基于时间延迟双向耦合混沌系统的控制,可以得到混沌系统实现同步的耦合参数范围。本文运用时间延迟反馈法,通过选择合适的延迟时间,在参数范围内,可将无标度动力系统控制到平衡点,数值模拟显示此方法鲁棒。此方法适用于普遍的复杂动态网络。
关 键 词: 理论物理;时间延迟;平衡点;同步

Abstract: Complex networks have been focused on by scientists from various fields. Recently, the synchronization of complex networks attracts more and more interests. Time delay feedback method is usual to achieve synchronization. Based on the control of time-delay bidirectional coupled chaotic systems, the scope of coupling parameters can be obtained. This paper uses a time delay feedback method to control a scale-free dynamical network to its equilibrium by choosing appropriate time delay in the parameter scope. Numerical simulations denote its Robustness. And this method is applicable to global complex dynamical networks.
Key words: theoretical physics; time delay; equilibrium; synchronization
