The complex braid of communication and control

Seminar: Communications and Networking | May 10 | 3-4 p.m. | Cory Hall, 400 Cory Hall

Next generation cyber-physical systems challenge the standard assumption of classical control theory that communication can be performed instantaneously, reliably, and with infinite precision. This motivated, at the turning of the millennium, the birth of a new chapter of control theory relating the ability to control dynamical systems to the characteristics of the communication channels used in the feedback loop. Potential applications of the theory include remote robot control, automated highway navigation using wireless sensor systems, automatic control for unmanned aerial vehicles, and design of critical energy, transportation, and health care systems. In this talk we review a series of contributions at the intersection of information and control theories, briefly describe applications, sketch mathematical arguments, and illustrate the main information-theoretic and control-theoretic tools used to derive these results. We also draw a connection between control over networks and some recent advancements in feedback communication, and mention some open problems in the field.
