Résumé : his thesis investigates how to save energy in wireless Networked Control Systems with control and communication co-design. This thesis reviews existing techniques and approaches that are used to save energy from a communication and a control point of view. Then a joint radio-mode management and feedback law policy is derived. The radio-mode management exploits the capabilities of the radio chip to switch to low consuming radio-modes to save energy, and to adapt the transmission power to the channel conditions. This results in an event-based control scheme where the system runs open loop at certain time. The joint policy is derived in the framework of Optimal Control with the use of Dynamic Programming. Stability of the closed loop system is investigated with Input-to-State Stability framework. The main conclusion of this thesis, is that cross-layer design in Networked Control System is essential to save energy in the wireless nodes.
