日時:平成17年3月16日(水)午後1時半より

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.
