Strategic Sensors and Regional Exponential Observability

Abstract EN

The aim of this paper is to introduce the concept of regional exponential observability in connection with the strategic sensors.

Then, we give characterization of such sensors in order that regional exponential observability can be achieved.

The obtained results are applied to two-dimensional systems, and various cases of sensors are considered.

We also show that there exists a dynamical system for diffusion system which is not exponentially observable in the usual sense but it may be regionally exponentially observable.
