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…
A bisector line field approach to interpolation of orientation fields
Nicolas Boizot, Ludovic Sacchelli
We propose an approach to the problem of global reconstruction of an orientation field. The method is based on a geometric model called "bisector line fields", which maps a pair of…
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…
