摘要：
In this paper, we propose feedback methods for controlling spatio-temporal on-off intermittency which is ail aperiodic switching between ail "off" state and ail "on" state. Diffusively coupled map lattice with spatially lion-uniform random driving is used for showing spatio-temporal on-off intermittency. For this purpose, we apply three different feedbacks. First, we use a linear feedback which is a simple method but has a long transient time. To overcome this problem, two nonlinear feedbacks based on prediction strategy are proposed. An important advantage of the methods is that the feedback signal is vanished when control is realized. Simulation results show that all methods have suppressed the chaotic behavior.
