Output feedback stabilization of non-uniformly observable systems by means of a switched Kalman-like observer
Lucas Brivadis, Ludovic Sacchelli
We propose to explore switching methods in order to recover some properties of Kalmanlike observers for output feedback stabilization of state-affine systems that may present obser…
Approximate observability and back and forth observer of a PDE model of crystallisation process
Lucas Brivadis, Ludovic Sacchelli
In this paper, we are interested in the estimation of Particle Size Distributions (PSDs) during a batch crystallization process in which particles of two different shapes coexist a…
New inversion methods for the single/multi-shape CLD-to-PSD problem with spheroid particles
Lucas Brivadis, Ludovic Sacchelli
In this paper, we express the Chord Length Distribution (CLD) measure associated to a given Particle Size Distribution (PSD) when particles are modeled as suspended spheroids in a…
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…
