On forced oscillations in lossless propagation models
Résumé
This paper focuses on forced oscillations (periodic and almost periodic) in some dynamical models described by coupled differential and difference equations. The existence and stability result is based on a theorem on invariant manifolds Banach spaces due to Kurzweil and Halanay. The state-space (based on Liapunov-Krasovskii functionals combined with the 5-procedure) approach is considered. An illustrative example is presented and some conclusions are drawn concerning sharpness and easiness in applications of the method. © 2001 EUCA.
