Optimal radio mode control for intelligent sensors nodes in NCS

Carlos Canudas-de-Wit, CNRS Grenoble, France

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 control and eventbased control, allowing to turn off the radio of the nodes, which is the main energy consumer, on longer time intervals than in the periodic case. While the existing literature only addresses policies using two radio-modes (Transmitting and Sleep), this contribution considers intermediate radio-modes, which consume more energy than the Sleep mode but have cheaper transition costs to the Transmitting
mode. We propose an event-based radio-mode switching policy to perform a trade-off between energy saving and performance of the control application. The switching policy is derived jointly with the feedback law using a switched model taking into account control and communication. We compute the optimal joint switching policy and feedback law using Dynamic Programming and we illustrate the results in simulations.

Biography:

Canudas-de-Wit, Carlos was born in Villahermosa, Tabasco, Mexico in 1958. He received his B.Sc. degree in electronics and communications from the Technological Institute of Monterrey, Mexico in 1980. In 1984 he received his M.Sc. in the Department of Automatic Control, Grenoble, France. He was visitor researcher in 1985 at Lund Institute of Technology, Sweden. In 1987 he received his Ph.D. in automatic control from the Polytechnic of Grenoble (Department of Automatic Control), France. Since then he has been working at the same department as "Directeur de recherche at the CNRS", where He teaches and conducts research in the area of nonlinear control of mechanical systems, and on networked controlled systems.  He is the current leader of the NeCS INRIA-GIPSA-lab team on Networked controlled systems. His research topics includes: vehicle control, adaptive control, identification, control of walking robots,  systems with friction, AC and CD drives, and networked controlled systems. He has established several industrial collaboration projects with major French companies (FRAMATOME, EDF, CEA, IFREMER, RENAULT, SCHNEIDER, ILL, IFP). He has written a book in 1988 on adaptive control of Partially known systems: theory and applications (Elservier Publisher). He has also edited a book in 1991 on Advanced Robot Control (Springer-Verlag),  a joint 12 author book "Theory of robot control", on Springer Control and Communication Series, in (1997). He has been associate editor of the IEEE-Transaction on Automatic Control, from Jan 1992, to Dec. 1997, and of AUTOMATICA, from 1999, to 2002.  His research publications includes: more than 120 International conference papers, and more than 47 published papers in international journals. He has supervised  20 Ph. D. students. He is current vise-president of the EUCA association, and serves at the IEEE Board of Governors 2011-2014.
