Delay effects on stability a survey
Résumé
In this paper, some recent progress on stability, robust stability and control techniques on time-delay systems are outlined. The goal is to give an overview of the techniques encountered in the analysis and design of delay systems. The key point is the analysis of the effects of delays on the (closed-loop) system properties. Some open problems will be also discussed. This survey paper complements the guided tours presented in [42, 30, 45]. A different control perspective can be found in [53].
