Jointly Equivariant Dynamics for Interacting Particles
Alain Ajami, Jean-Paul Gauthier, Francesco Rossi
Let a finite set of interacting particles be given, together with a symmetry Lie group . Here we describe all possible dynamics that are jointly equivariant with respect to the…
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…
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…
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…
