Filtering Homogeneous Observer for MIMO System

no code implementations6 Jan 2024 Xubin Ping, Konstantin Zimenko, Andrey Polyakov, Denis Efimov

Homogeneous observer for linear multi-input multi-output (MIMO) system is designed.

Learning linear dynamical systems under convex constraints

no code implementations27 Mar 2023 Hemant Tyagi, Denis Efimov

We consider the problem of finite-time identification of linear dynamical systems from $T$ samples of a single trajectory.

Stability analysis and stabilization of systems with hyperexponential rates

no code implementations16 Jul 2022 Konstantin Zimenko, Denis Efimov, Andrey Polyakov

Hyperexponential stability is investigated for dynamical systems with the use of both, explicit and implicit, Lyapunov function methods.

Consistent discretization of finite/fixed-time controllers

no code implementations7 Jul 2022 Andrey Polyakov, Denis Efimov, Xubin Ping

The paper proposes an algorithm for a discretization (sampled-time implementation) of a homogeneous control preserving the finite-time and nearly fixed-time stability property of the original (sampling-free) system.

On annular short-time stability conditions for generalized Persidskii systems

no code implementations15 Apr 2022 Wenjie Mei, Denis Efimov, Rosane Ushirobira

This paper studies the trajectory behavior evaluation for generalized Persidskii systems with an essentially bounded input on a finite time interval.

Robust-Adaptive Interval Predictive Control for Linear Uncertain Systems

no code implementations20 Jul 2020 Edouard Leurent, Denis Efimov, Odalric-Ambrym Maillard

We consider the problem of stabilization of a linear system, under state and control constraints, and subject to bounded disturbances and unknown parameters in the state matrix.

Robust-Adaptive Control of Linear Systems: beyond Quadratic Costs

no code implementations NeurIPS 2020 Edouard Leurent, Denis Efimov, Odalric-Ambrym Maillard

We consider the problem of robust and adaptive model predictive control (MPC) of a linear system, with unknown parameters that are learned along the way (adaptive), in a critical setting where failures must be prevented (robust).

Interval Prediction for Continuous-Time Systems with Parametric Uncertainties

no code implementations9 Apr 2019 Edouard Leurent, Denis Efimov, Tarek Raïssi, Wilfrid Perruquetti

The problem of behaviour prediction for linear parameter-varying systems is considered in the interval framework.
