基于Lyapunov稳定性理论,将单个Lorenz系统的一种追踪控制方案用于单向耦合网络连接的Lorenz系统.只对网络系统的一个节点加入控制器,就实现了单向耦合网络连接的Lorenz系统的单个输出变量对任意给定参考信号的追踪.数值仿真表明,当网络的耦合强度足够大时,可以实现包括同结构和异结构系统信号之间的有效追踪.
Based on Lyapunov stability theory, a tracking control scheme for single Lorenz system is used to the tracking control of Lorenz systems in unidirectional coupling network. A controller put on one node of this network suffices to realized tracking of some output signals of this network to approach to any desired orbit. Computer simulation shows that tracking controls can be realized even for different chaotic systems as long as the unidirectional coupling strength is large enough.
