Interval methods in control engineering

Abstract:
The talk addresses interval state estimation in networked control systems. There has been a significant development of embedded and networked control systems, where sensor and control data are transmitted over digital communication channels. To reduce the communication load on these limited bandwidth channels, it is tempting to exchange data in an aperiodic manner. Besides, the presence of sampling jitters, packet dropouts and fluctuations in network accessibility further emphasized the interest in time-varying and aperiodic sampling.
The talk objectives are twofold: 1) introduces the concept of interval impulsive observer, a new framework for interval state estimation for continuous dynamical systems from discrete-time measurements, 2) show how to use interval impulsive observers for designing robust interval with either aperiodic or event-triggered sampling.
This is a work jointly conducted with Dr. Djahid Rabehi (PRISME – Univ. Orleans) and Dr. Nacim Meslem (GIPSA Lab).
