External Presentation (External Speaker)
This work considers the scheduling problem of a decentralized system where a number of dynamical subsystems with no computational power are scheduled to transmit their measurements via a resource-limited communication network to a remote decision maker who acts as an estimator, controller and scheduler for the subsystems. We propose a new approach for communication resource allocation for a wide class of objective functions, for both coupled and decoupled systems, and for both scheduling observations as well as control commands. This framework allows to schedule over a finite horizon and can explicitly deal with stochastic channels. For decoupled subsystems, we propose the notion of cost of information loss (CoIL) and we demonstrate that the communications resource allocation problem can be directly expressed in terms of CoIL functions as an assignment-type optimization problem. Illustrative examples demonstrate how communication resources affect the performance of the system.
About Themistoklis Charalambous
Themistoklis Charalambous received the B.A. and M.Eng. degrees in electrical and information sciences from Cambridge University, Cambridge, U.K., in 2005. He received the Ph.D. degree in the Control Laboratory, of the Engineering Department, Cambridge University in 2010. He worked as a research associate at Imperial College London, as a Visiting Lecturer at the Department of Electrical and Computer Engineering, University of Cyprus, and as a post-doctoral researcher at the Automatic Control Lab of the School of Electrical Engineering at the Royal Institute of Technology (KTH) and at the Department of Electrical Engineering at Chalmers University of Technology. He is currently an Assistant Professor at the Department of Electrical Engineering and Automation, School of Electrical Engineering, Aalto University and an Academy of Finland Research Fellow. His research involves distributed coordination and control, distributed decision making, and control to various resource allocation problems in complex and networked systems.
