FeedNetBack D03.05 - Networking Protocols for Control
Résumé
This report documents the research work carried out for Task 3.4. on networking protocols for control. The main objective is to design and study radio networking protocols which are adapted to fit a given control application. Accordingly, most of the work deals with a resource optimization problem under the constraint of strict delay constraints and allowable packed loss rate where a high-level model of the communication network is assumed. Three different approaches are taken. First, we optimize the instantaneous communication rate allocation for state feedback control over noisy channels using high-rate approximation theory. Second, we present a framework for the joint design of controllers and a network for multiple control systems where the sensor measurements are transmitted to the controller over the IEEE 802.15.4 wireless network, which considers the critical aspects for both control and communication systems. Lastly, we study cooperative data detection where a CDMA protocol is used for exchange information between nodes grouped in two clusters, which results in a distributed version of Alternating Least Squares algorithm using average consensus iterations.
