A propagating wave segment in an excitable medium has attracted attention as one of interesting spatio-temporal phenomena in reaction-diffusion systems. The wave segment has to be stabilized with feedback control because of its instability. The previous studies adjusted the controller parameters without consideration of the dynamics of the wave segment. In the present report, we identify a mathematical model describing the dynamics of the wave segment. The frequency response of the identified model agrees closely with that of the wave segment. Furthermore, we design a two-degree-of-freedom control system on the basis of the identified model. We show on numerical simulations that the performance of control is dramatically improved. |
