Output feedback stabilisation of bilinear systems via control templates
Ludovic Sacchelli, Lucas Brivadis, Ulysse Serres +1
We establish a separation principle for the output feedback stabilisation of state-affine systems that are observable at the stabilization target. Relying on control templates (rec…
Exponential stabilizability and observability at the target imply semiglobal exponential stabilizability by templated output feedback
Vincent Andrieu, Lucas Brivadis, Jean-Paul Gauthier +2
For nonlinear analytic control systems, we introduce a new paradigm for dynamic output feedback stabilization. We propose to periodically sample the usual observer based control la…
Generalized Lyapunov conditions for k-contraction: analysis and feedback design
Andreu Cecilia, Samuele Zoboli, Daniele Astolfi +2
Recently, the concept of k-contraction has been introduced as a promising generalization of contraction for dynamical systems. However, the study of k-contraction properties has fa…
New perspectives on output feedback stabilization at an unobservable target
Lucas Brivadis, Jean-Paul Gauthier, Ludovic Sacchelli +1
We address the problem of dynamic output feedback stabilization at an unobservable target point. The challenge lies in according the antagonistic nature of the objective and the pr…
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…
