場所:京都大学工学部総合校舎2階213講義室
講演者:Prof. Hartmut Benner (TU Darmstadt)
講演題目:
Time-Delayed Feedback Control: Theory and Application
講演要旨:
We review recent developments for the control of chaos by time-delayed feedback methods. While such methods are easily applied even in quite complex experimental context the theoretical analysis yields infinite-dimensional differential-difference systems which are hard to tackle. The essential ideas for a general theoretical approach are sketched and the results are compared with electronic circuits and with high power ferromagnetic resonance experiments. We also discuss the influence of global properties, e. g. the basins of attraction of the controlled states. Our results show that the control performance can be understood on the basis of experimentally accessible quantities without resort to any model for the internal dynamics.
