We consider networks of chaotic maps with different network topologies. In each case, they are coupled in such a way as to generate synchronized chaotic solutions. By using the methods of control of chaos we are controlling a single map into a predetermined trajectory. We analyze the reaction of the network to such a control. Specifically we show that a line of one-dimensional logistic maps that are unidirectionally coupled can be controlled from the first oscillator whereas a ring of diffusively coupled maps cannot be controlled for more than 5 maps. We show that rings with more elements can be controlled if every third map is controlled. The dependence of unidirectionally coupled maps on noise is studied. The noise level leads to a finite synchronization lengths for which maps can be controlled by a single location. A two-dimensional lattice is also studied.
我们考虑具有不同网络拓扑结构的混沌映射网络。在每种情况下,它们以能产生同步混沌解的方式进行耦合。通过使用混沌控制方法,我们将单个映射控制到预定轨迹。我们分析网络对这种控制的反应。具体而言,我们表明单向耦合的一维逻辑斯蒂映射线可以从第一个振荡器进行控制,而扩散耦合映射环对于超过5个映射则无法进行控制。我们表明,如果每隔第三个映射进行控制,具有更多元素的环是可以控制的。研究了单向耦合映射对噪声的依赖性。噪声水平导致了有限的同步长度,在此长度内映射可以通过单个位置进行控制。还研究了二维晶格。
