Adaptive tracking control of Euler-Lagrange systems with bounded controls
(2016)"We solve the simultaneous closed?loop identification and tracking?control problems for fully actuated Euler-Lagrange systems under input constraints. We use a nonlinear adaptive controller reminiscent of computed?torque?type ... -
Adaptive tracking via pinning in networks of nonidentical nodes
(2018)"We investigate the control of dynamical networks for the case of nodes, that although different, can be make passive by feedback. The so-called V-stability characterization allows for a simple set of stabilization conditions ... -
An algorithm based on 3-braids to solve tangle equations arising in the action of Gin DNA invertase
(2010-03)"The tangle model of Ernst and Sumners is an effective tool in the topological analysis of enzymes, a particular application of which aims at deducing the mechanism of action of site-specific recombination mediated by the ... -
An analytical study of the logarithmic mean temperature difference
(2005)"La media logarítmica de diferencia de temperaturas (LMTD, por sus siglas en inglés) ha causado inconveniencias en diversas aplicaciones tales como ciertos programas de simulación de procesos. Su forma indeterminada es una ... -
An output-feedback global continuous control scheme with desired gravity compensation for the finite-time and exponential regulation of bounded-input robotic systems
(International Federation of Automatic Control, 2018)"A Saturating-Proportional Saturating-Derivative type global continuous control scheme with desired gravity compensation for the finite-time or (local) exponential stabilization of robotic systems with constrained inputs, ... -
An upper limit for slow-earthquake zones: self-oscillatory behavior through the Hopf bifurcation mechanism from a spring-block model under lubricated surfaces
(2017)"The complex oscillatory behavior of a spring-block model is analyzed via the Hopf bifurcation mechanism. The mathematical spring-block model includes Dieterich Ruina's friction law and Stribeck's effect. The existence of ... -
Analog electronic implementation of a class of hybrid dissipative dynamical system
(2016)"An analog electronic implementation by means of operational amplifiers of a class of hybrid dissipative systems in R3R3 is presented. The switching systems have two unstable hyperbolic focus-saddle equilibria with the ... -
Analysis of a class of complex system without equilibria via switched control law
(International Federation of Automatic Control, 2018)"In this article we introduce a new class of complex system without equilibria which exhibits a chaotic multiscroll attractor in each node. The number of scrolls in the attractor is determined by a switched control law to ... -
Analysis of a model for the morphological structure of renal arterial tree: fractal structure
(Hindawi, 2013)"One of the fields of applied mathematics is related to model analysis. Biomedical systems are suitable candidates for this field because of their importance in life sciences including therapeutics. Here we deal with the ... -
Applying graph theory to arterial vascular tree of the kidney
(2009)"The renal vascular development occurs through vasculogenesis and/or angiogenesis. Particularly, there are two types of vascular angiogenesis: sprouting and splitting. We show the graphs can generate binary tree structures ... -
Bistable behavior via switching dissipative systems with unstable dynamics and its electronic design
(International Federation of Automatic Control, 2018)"In this work we present a design of a bistable system and its electronic circuit which is generated by a switching system. The switching system is comprised by dissipative subsystems with unstable dynamics based on the ... -
Bounded positive control for double-pipe heat exchangers
(2009)"In this work, an outlet temperature control scheme for double-pipe heat exchangers is proposed. Compared to previously proposed approaches, the algorithm developed here takes into account and actually exploits the analytical ... -
