Equivariant Pyragas control

Isabelle Schneider


In this talk I show how the concept of Pyragas control can be adapted to dynamical systems near equivariant Hopf bifurcation. The aim is to introduce a delayed feedback control term which uses the spatio-temporal symmetry of the unstable periodic orbit. I want to show how the control regions look and give a summary of the proof of stabilization. For the remaining eigenvalues, it is possible to find necessary conditions for the stabilization, which also imply a limitation of the original Pyragas control scheme.
