Learning linear dynamical systems under convex constraints
Hemant Tyagi, Denis Efimov
We consider the problem of finite-time identification of linear dynamical systems from samples of a single trajectory. Recent results have predominantly focused on the setup wh…
Stability analysis and stabilization of systems with hyperexponential rates
Konstantin Zimenko, Denis Efimov, Andrey Polyakov
Hyperexponential stability is investigated for dynamical systems with the use of both, explicit and implicit, Lyapunov function methods. A nonlinear hyperexponential control is des…
Consistent discretization of finite/fixed-time controllers
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 t…
On annular short-time stability conditions for generalized Persidskii systems
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. Also, the notions of annular s…
State Observation of Affine-in-the-States Systems with Unknown Time-Varying Parameters and Output Delay
Alexey Bobtsov, Nikolay Nikolaev, Romeo Ortega +2
In this paper we address the problem of adaptive state observation of affine-inthe-states time-varying systems with delayed measurements and unknown parameters. The development of…
Adaptive Finite-time and Fixed-time Control Design using Output Stability Conditions
Konstantin Zimenko, Denis Efimov, Andrey Polyakov
The present paper provides a sufficient condition to ensure output finite-time and fixed-time stability. Comparing with analogous researches the proposed result is less restrictive…
