In the finite-dimensional case, we propose a family of fast oscillating feedback controls that stabilize the equilibrium with exponential decay rate. The idea of proof is based on an extension of Lyapunov’s direct method and the Chen-Fliess series. A characterization of attractors of infinite-dimensional closed-loop systems is obtained by the invariance principle. These results are applied for the stabilization of nonholonomic systems and mathematical models of controlled flexible structures.Vortragende(r)Prof. Dr. Alexander ZuyevKontaktSenka Haznadar (senka.haznadar@aau.at)
