New dynamical observer for a batch crystallization process based on solute concentration
Vincent Andrieu, Emilie Gagnière, Elodie Chabanon +4
In this paper a new observer is introduced to estimate the Crystal Size Distribution (CSD) only from the measurements of the solute concentration, temperature and a model of the gr…
From local to global asymptotic stabilizability for weakly contractive control systems
Vincent Andrieu, Lucas Brivadis, Jean-Paul Gauthier +2
A nonlinear control system is said to be weakly contractive in the control if the flow that it generates is non-expanding (in the sense that the distance between two trajectories i…
Luenberger observers for infinite-dimensional systems, Back and Forth Nudging and application to a crystallization process
Lucas Brivadis, Vincent Andrieu, Ulysse Serres +1
This paper deals with the observer design problem for time-varying linear infinite-dimensional systems. We address both the problem of online estimation of the state of the system…
Luenberger observers for discrete-time nonlinear systems
Lucas Brivadis, Vincent Andrieu, Ulysse Serres
In this paper, we consider the problem of designing an asymptotic observer for a nonlin-ear dynamical system in discrete-time following Luenberger's original idea. This approach is…
Dynamic Output Feedback Stabilization of Non-uniformly Observable Dissipative Systems
Ludovic Sacchelli, Lucas Brivadis, Vincent Andrieu +2
Output feedback stabilization of control systems is a crucial issue in engineering. Most of these systems are not uniformly observable, which proves to be a difficulty to move from…
Homogeneous Approximation, Recursive Observer Design, and Output Feedback
Vincent Andrieu, Laurent Praly, Alessandro Astolfi
We introduce two new tools that can be useful in nonlinear observer and output feedback design. The first one is a simple extension of the notion of homogeneous approximation to ma…
