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…
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…
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…
Avoiding observability singularities in output feedback bilinear systems
Lucas Brivadis, Jean-Paul Gauthier, Ludovic Sacchelli +1
Control-affine output systems generically present observability singularities, i.e. inputs that make the system unobservable. This proves to be a difficulty in the context of outpu…
