Asymptotic regional state reconstruction

The aim is to explore the concept of regional asymptotic observation for a class of parabolic-distributed parameter systems. The approach derives from Luenberger observer type, as introduced by Gressang and Lamont (1975). We show the links with regional detectability and strategic sensors. We also show that there is a dynamical system that is not observer in the usual sense, but that may be regional observer. Furthermore, we consider the use of regional observers in regional closed-loop control systems.

Regional observability and sensor structures

Abstract In various distributed systems we are interested in the knowledge of the state of a given sub-region. The aim of this paper is to introduce the concept of regionally strategic sensors for a class of distributed parameter systems. This emphasizes the spatial structure and location of the sensors in order that regional observability can be achieved. For different geometrical situations we give the characterization of regional strategic sensors. We also give the dual results for the characterizations of regional strategic actuators.

Sensors and actuators in distributed systems

The concepts of strategic sensors and actuators are introduced for a class of distributed parameter systems. This emphasizes the spatial structure and location of the sensors and controls in order that observability and controllability can be achieved.
