| Research Abstract |
This study proposes a few control methods for suppressing nonlinear phenomena, such as spiral waves and spatiotemporal chaos, in spatiotemporal systems. The following systems are employed as controlled objects : a cellular automata model of excitable media, coupled map lattices on irregular network topologies, excitable media with nonexcitable cells, and a piecewise linear FitzHugh-Nagumo model. The superiority of our methods is provided from a viewpoint of control theory.
