Input-to-state stability of infinite-dimensional systems: Foundations and present-day developments

no code implementations4 Jun 2024 Andrii Mironchenko, Christophe Prieur

Input-to-state stability (ISS) unifies the stability and robustness in one notion, and serves as a basis for broad areas of nonlinear control theory.

Adaptive Boundary Control of the Kuramoto-Sivashinsky Equation Under Intermittent Sensing

no code implementations26 Mar 2024 Mohamed Camil Belhadjoudja, Mohamed Maghenem, Emmanuel Witrant, Christophe Prieur

In contrast, when the state is measured at every spatial point all the time (full state measurement), convergence to an arbitrarily-small neighborhood of the origin is guaranteed, even if the perturbation's maximal size is unknown.

Improving a Proportional Integral Controller with Reinforcement Learning on a Throttle Valve Benchmark

no code implementations21 Feb 2024 Paul Daoudi, Bojan Mavkov, Bogdan Robu, Christophe Prieur, Emmanuel Witrant, Merwan Barlier, Ludovic Dos Santos

This paper presents a learning-based control strategy for non-linear throttle valves with an asymmetric hysteresis, leading to a near-optimal controller without requiring any prior knowledge about the environment.

A Conservative Approach for Few-Shot Transfer in Off-Dynamics Reinforcement Learning

1 code implementation24 Dec 2023 Paul Daoudi, Christophe Prieur, Bogdan Robu, Merwan Barlier, Ludovic Dos Santos

In the few-shot framework, a limited number of transitions from the target environment are introduced to facilitate a more effective transfer.

Fusion of Distance Measurements between Agents with Unknown Correlations

no code implementations9 Jun 2023 Colin Cros, Pierre-Olivier Amblard, Christophe Prieur, Jean-François da Rocha

To optimally integrate a distance measurement between two users into a navigation filter, the correlation between the errors of their estimates must be known.

Synchronization of Identical Boundary-Actuated Semilinear Infinite-Dimensional Systems

no code implementations14 Apr 2021 Francesco Ferrante, Giacomo Casadei, Christophe Prieur

For this class of systems, sufficient conditions in the form of linear matrix inequalities for the design of synchronizing policies are provided.

Stability analysis of reaction-diffusion PDEs coupled at the boundaries with an ODE

no code implementations8 Mar 2021 Hugo Lhachemi, Christophe Prieur

This paper addresses the derivation of generic and tractable sufficient conditions ensuring the stability of a coupled system composed of a reaction-diffusion partial differential equation (PDE) and a finite-dimensional linear time invariant ordinary differential equation (ODE).

Finite-dimensional observer-based PI regulation control of a reaction-diffusion equation

no code implementations9 Dec 2020 Hugo Lhachemi, Christophe Prieur

The proposed control strategy consists of the coupling of a finite-dimensional observer and a PI controller in order to achieve the boundary setpoint regulation control of various system outputs such as the Dirichlet and Neumann traces.
