The main results of the present work constitute generalizations of a well-known result towards feedback stabilization due to J. M. Coron and L. Rosier concerning stabilization of autonomous systems by means of time-varying periodic feedback.Submitted for possible publication to ESAIM Control, Optimisation and Calculus of VariationsOptimization and Controltext
