Figure 4: Separate synchronous variables , , of different network models where are shown by the red line, are shown by the blue line, and are shown by the green line. ; . The dynamics of nodes satisfy the Lü system. The nodes are controlled by the adaptive controllers (20) and (21). The network models of (a)–(d) are the same with Figures 1(a)1(d) (color online).
