摘要：
In the paper,we study effects of scale-free （SF） topology on dynamical synchronization and control incoupled map lattices （CIVIL）.Our strategy is to apply three feedback control methods,including constant feedbackand two types of time-delayed feedback,to a small fraction of network nodes to reach desired synchronous state.Twocontrolled bifurcation diagrams verses feedback strength are obtained respectively.It is found that the value of criticalfeedback strength γ;for the first time-delayed feedback control is increased linearly as e is increased linearly.The CIVILwith SF loses synchronization and intermittency occurs if γ>γ;.Numerical examples are presented to demonstrate allresults.
