New results on robust exponential stability of integral delay systems
(2016-06)"The robust exponential stability of integral delay systems with exponential kernels is investigated. Sufficient delay-dependent robust conditions expressed in terms of linear matrix inequalities and matrix norms are derived ... -
Non-alternating knots: alternation and dealternating numbers
(2017-08)"In this thesis we give formulae to obtain the HOMFLY-PT polynomial of certain oriented 3-tangles and links formed by the closure of them. Also we show formulae for the Conway-Alexander polynomial. We propose a construction ... -
Nonclassical point of view of the Brownian motion generation via fractional deterministic model
(2018)"In this paper, we present a dynamical system based on the Langevin equation without stochastic term and using fractional derivatives that exhibit properties of Brownian motion, i.e. a deterministic model to generate ... -
Nonlinear and robust control strategy based on chemotherapy to minimize the HIV concentration in blood plasma
(2016)"A nonlinear PI-type control strategy is designed in order to minimize the HIV concentration in blood plasma, via medical drug injection, under the framework of bounded uncertain input disturbances. For control design it ... -
Nonlinear filtering preserves chaotic synchronization via master-slave system
(2013)"We present a study on a class of interconnected nonlinear systems and give some criteria for them to behave like a filter. Some chaotic systems present this kind of interconnected nonlinear structure, which enables the ... -
Nonlinear voltage regulation strategy for a fuel cell/supercapacitor power source system
(IEEE, 2018)"The main purpose of this work is to model and control a fuel cell/supercapacitor power source system to feed a DC-bus with a constant output voltage despite load changes. The fuel cell is modeled as a nonlinear current-dependent ... -
Numerical computation of Lyapunov matrices for integral delay systems
(2017)"This paper focuses on the problem of computing Lyapunov matrices for integral delay systems. It is shown that these Lyapunov matrices cannot be computed by means of the existing methods for Lyapunov matrices of differential ... -
Observer-less output-feedback global continuous control for the finite-time and exponential stabilization of mechanical systems with constrained inputs
(2017)"An observer-less output-feedback global continuous control scheme for the finite-time or (local) exponential stabilization of mechanical systems with constrained inputs is proposed. The approach is formally developed ... -
On Brusselator and Oregonator as chemical reaction networks: a graph approach
(2009)"This paper shows graph similarities between Brusselator and Oregonator reaction mechanisms, using the jacobian matrix in convex coordinates as an adjacency matrix which defines a weighted directed pseudograph. A linear ... -
On computing estimates of the attraction region for a class of nonlinear time-delay systems
(2006)"In this paper, initial estimates of the attraction region for a class of nonlinear time delay systems are proposed. The approach is constructive, and make use of an appropiate Lyapunov-Krasovskii functional. Several ... -
On friction effects as a mechanism to induce complex dynamical behavior in earthquakes
(2012)"In this paper we analyze a nonlinear dynamical system that describes the kinetic mechanism between tectonic plates on the crust´s earth undergoing stick slip movement. The analysis includes friction effects and an empirical ... -
On modeling and control of multilevel converters and PLL algorithms.
(2009)"The present thesis is focuses in the study of the multilevel converters and the the phaselocked loop algorithms. In the first five chapters, two of the main topologies of multilevel converters are studied, namely, diode ... -
On multistability behavior of unstable dissipative systems
(2018)"We present dissipative systems with unstable dynamics called the unstable dissipative systems which are capable of generating a multi-stable behavior, i.e., depending on its initial condition, the trajectory of the system ... -
On repetitive control for harmonic compesation in power electronic systems
(2007)"Para atacar el problema de distorsión armónica distintas técnicas de control han sido utilizadas, entre las que destacan: el control por modos deslizantes, los controladores basados en pasividad, el control adaptable, los ... -
On stability of integral delay systems
(2010-12)"The exponential stability of a class of integral delay systems is investigated by using the Lyapunov–Krasovskii functional approach. Sufficient delay-dependent stability conditions and exponential estimates for the solutions ... -
On suitable observables for the chaotic Peroxidase-Oxidase autocatalytic reaction
(International Federation of Automatic Control, 2018)"Neurodegenerative diseases such as Alzheimer’s and Parkinson present oxidative damage of neurocytes generally caused by reactive oxygen species (ROS). Heme peroxidases consume and produce ROS thus serving as suppresors ... -
On the controllability of networks with nonidentical linear nodes
(Oxford University Press, 2016)"The controllability of dynamical networks depends on both network structure and node dynamics. For networks of linearly coupled linear dynamical systems the controllability of the network can be determined using the ... -
