Control of chaotic solitons by time delay feedback
Piotr Fronczak and Janusz Holyst
We investigate a control of chaotic solitons using a modified
time-delayed autosynchronization method. Numerical results for
the maximal Lyapunov exponent are in very good agreement with
analytical theory developed originally for low dimensional
systems. The control is most efficient when the spatial
distribution of the control force is proportional to the kink
translational mode. Observations of the motion of the kink centre
and the total power transmitted to the system lead to the same
values of the maximal Lyapunov exponent.
