Abstract: Energy efficiency is one of the main issues in wireless Networked Control Systems. The control community has already shown large interest in the topics of intermittent estimation and control, allowing to turn off the radio of the nodes which is the main energy consumer. While the existing literature only addresses policies using two radio-modes (ON/OFF), this paper considers intermediate radio-modes (\eg IDLE), which consume less energy than the ON mode and offer better reactivity than the OFF mode, but introduce transition costs. The objective of the paper is to discuss the relevance and benefit to use low consuming radio-modes and to propose a mode switching policy to perform a trade-off between energy savings and performance of the control application in the case where we have a finite horizon. We propose two possible algorithms which solve this using dynamic programming, and then test them with an example of an application.

%2 La consommation d'énergie est l'un des principaux problèmes dans les Systèmes de Contrôle en Réseaux. La communauté de contrôle a déjà montré beaucoup d'intérêt pour les estimations et contrôles intermittents, en permettant d'éteindre la radio qui est le composant qui consomme le plus. La littérature existante n'adresse que les systèmes avec deux modes (ON,OFF).Ce papier considère des modes intermédiaires (\eg IDLE), qui consomment moins d'énergie que ON et offrent une meilleure réactivité que OFF, mais qui introduit des coups de transition. L'objectif de ce papier est d'étudier les effets et les avantages d'utiliser des modes intermédiaires et de proposer une méthode pour décider quand changer de mode pour avoir un On propose deux algorithmes qui résolvent ce problème et ensuite on les teste avec un exemple d'une application.
