Causality study and numerical response of the magnetic permeability as a function of the frequency of ferrites using Kramers–Kronig relations
(2008)"In this paper, the numerical treatment of magnetic loss of NiZn, MnZn, Ni2Y, and NiZnCu ferrite and their composites, by using Krameres–Kronig relations, is investigated. The complex magnetic permeability spectra for ... 
A characterization of Integral ISS for switched and timevarying systems
(201802)"Most of the existing characterizations of the integral inputtostate stability (iISS) property are not valid for timevarying or switched systems in cases where converse Lyapunov theorems for stability are not available. ... 
Diseño de observadores en modos cuasideslizantes vía LMIs
(200807)"En este trabajo se presenta un observador robusto por modos cuasideslizantes para plantas con modelo nominal lineal e incertidumbres/pertubaciones de cierta clase particular. Las señales utilizadas para la estimación del ... 
An extension of LaSalle’s invariance principle for switched systems
(2006)"This paper addresses invariance principles for a certain class of switched nonlinear systems. We provide an extension of LaSalle’s Invariance Principle for these systems and state asymptotic stability criteria. We also ... 
Global stability results for switched systems based on weak Lyapunov functions
(201706)"In this paper we study the stability of nonlinear and timevarying switched systems under restricted switching. We approach the problem by decomposing the system dynamics into a nominallike part and a perturbationlike ... 
ISS implies iISS even for switched and timevarying systems (if you are careful enough)
(201906)"For timeinvariant systems, the property of inputtostate stability (ISS) is known to be strictly stronger than integralISS (iISS). Known proofs of the fact that ISS implies iISS employ Lyapunov characterizations of ... 
Learning and imitation: transitional dynamics in variants of the BAM
(2004)"We study the dynamics of selforganized systems when disturbed by shocks. For this purpose, we consider extensions of the “Bar Attendance Model” [1] (BAM), which provides a stylized setting for the analysis of the emergence ... 
Linear parametervarying model to design control laws for an artificial pancreas
(201802)"The contribution of this work is the generation of a controloriented model for insulinglucose dynamic regulation in type1 diabetes mellitus (T1DM). The novelty of this model is that it includes the timevarying nature, ... 
On some goodnessoffit tests and their connection to graphical methods with uncensored and censored data
(2019)"In this work, we present goodnessoffit tests related to the KolmogorovSmirnov and Michael statistics and connect them to graphical methods with uncensored and censored data. The AndersonDarling test is often empirically ... 
On zeroinput stability inheritance for timevarying systems with decayingtozero input power
(201706)"Stability results for timevarying systems with inputs are relatively scarce, as opposed to the abundant literature available for timeinvariant systems. This paper extends to timevarying systems existing results that ... 
Robustness properties of an algorithm for the stabilisation of switched systems with unbounded perturbations
(201705)"In this paper, it is shown that an algorithm for the stabilisation of switched systems introduced by the authors is robust with respect to perturbations which are unbounded in the supremum norm, but bounded in a powerlike ... 
Timevarying procedures for insulindependent Diabetes Mellitus control
(2011)"This work considers the problem of automatically controlling the glucose level in insulin dependent diabetes mellitus (IDDM) patients. The objective is to include several important and practical issues in the design: model ... 
Two classes of bipartite networks: nested biological and social systems
(2008)"Bipartite graphs have received some attention in the study of social networks and of biological mutualistic systems. A generalization of a previous model is presented, that evolves the topology of the graph in order to ... 
Uniform asymptotic stability of switched nonlinear timevarying systems and detectability of reduced limiting control systems
(2018)"This paper is concerned with the study of both, local and global, uniform asymptotic stability for switched nonlinear timevarying (NLTV) systems through the detectability of outputmaps. With this aim the notion of reduced ...

Uniform stability properties of switched systems with switchings governed by digraphs
(2005)"Characterizations of various uniform stability properties of switched systems described by differential inclusions, and whose switchings are governed by a digraph, are developed. These characterizations are given in ...
