Self-organization in a network of autonomous elements with adaptive coupling-design and control

We have constructed networks with various coupling laws, and investigated self-organization phenomena in such active systems and the control of such dynamics through various methods. In the coupled system of oscillatory or excited elements with time-delayed feedback, we have demonstrated that the collective dynamics, such as coherence resonance and phase synchronization, can be controlled by adjusting the delay time. In the adaptive network designed to change the coupling weights depending on the phase difference between oscillators, we have found that various cluster states appear according to the evolution law of the network.
