Active damping of a DC network with a constant power load: an adaptive passivity-based control approach
(2018)
Comunicació de congrés
Accés obertThis paper proposes a nonlinear, adaptive controller to increase the stability margin of a direct-current (DC) small-scale electrical network containing a constant power load, whose value is unknown. Due to their negative ... -
Bifurcation analysis of a Lyapunov-based controlled boost converter
(2013-11)
Article
Accés restringit per política de l'editorialLyapunov-based controlled boost converters have a unique equilibrium point, which is globally asymptotically stable, for known resistive loads. This article investigates the dynamic behaviors that appear in the system when ... -
Design of shifting output-feedback controllers for LPV systems subject to time-varying saturations
(2022)
Text en actes de congrés
Accés obertThis paper considers the problem of designing a shifting output-feedback controller for polytopic linear parameter-varying (LPV) systems subject to time-varying saturations. By means of the LPV framework and the use of the ... -
Design of shifting state-feedback controllers for LPV systems subject to time-varying saturations via parameter-dependent Lyapunov functions
(2022-07)
Article
Accés obertThis paper considers the problem of designing a shifting state-feedback controller via quadratic parameter-dependent Lyapunov functions (QPDLFs) for systems subject to symmetric time-varying saturations. By means of the ... -
Harmonic balance-based control of a boost DC/AC converter
(2012-08)
Article
Accés obertThe achievement of step-up inversion with a boost DC/AC converter requires appropriate periodic references for inductor currents, which have to satisfy ordinary differential equations (ODE) of the Abel type. These are ... -
On Lyapunov sampling for event-driven controllers
(2009)
Text en actes de congrés
Accés obertThis paper investigates an event condition for event-driven controllers based on Lyapunov functions. Considering that constant values of a Lyapunov function define contour curves that form closed regions around the equilibrium ... -
On the global stability of Takagi-Sugeno general model
(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1999)
Article
Accés obertGlobal stability of Takagi-Sugeno (T-S) fuzzy model is presented. First, stability conditions for T-S fuzzy model presented by Tanaka and Sugeno are reviewed. Second, new theorems for the stability of the general form of ... -
Separation of variables and explicit theta-function solution of the classical Steklov--Lyapunov systems: A geometric and algebraic geometric background
(2009-11)
Report de recerca
Accés obertAbstract The paper revises the separation of variables and explicit integration of the classical Steklov{ Lyapunov systems, which was ¯rst made by F. KÄotter in 1900. Namely, we give a geometric interpretation of the ... -
Stabilisation of state-and-input constrained nonlinear systems via diffeomorphisms: A Sontag's formula approach with an actual application
(2018-09-10)
Article
Accés obertIn this work, we provide a new and constructive outlook for the control of state-and-input constrained nonlinear systems. Previously, explicit solutions have been mainly focused on the finding of a barrier-like Lyapunov ... -
Stability of time-varying systems in the absence of strict Lyapunov functions
(2019-06-01)
Article
Accés obertWhen a non-linear system has a strict Lyapunov function, its stability can be studied using standard tools from Lyapunov stability theory. What happens when the strict condition fails? This paper provides an answer to that ...
