Estimates of the attraction region for a class of nonlinear time-delay systems
(2007)
"In this paper, we propose various estimates of the attraction region for a class of nonlinear time-delay systems of the form forumla The approach is constructive and makes use of a Lyapunov–Krasovskii functional associated ...
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 ...
Convertidor elevador: mapa unidimensional y dinámica no lineal
(2005)
"En esta contribución se realiza el desarrollo de un mapa discreto en el tiempo del convertidor elevador controlado en modo corriente pico a partir de sus formas de onda. Se presentan criterios de existencia de puntos ...
Speed-gradient adaptive high-gain observers for synchronization of chaotic systemsSpeed-gradient adaptive high-gain observers for synchronization of chaotic systems
(International Federation of Automatic ControlInternational Federation of Automatic Control, 2007)
"We address the problem of output feedback synchronization of certain chaotic systems, under parameter uncertainty. That is, given a master system, the objective is to design a slave system that copies the dynamics of the ...
Control of mechanical systems on Lie groups based on vertically transverse functions
(2008-06)
"The transverse function approach to control provides a unified setting to deal with practical stabilization and tracking of arbitrary trajectories for controllable driftless systems. Controllers derived from that approach ...
Reconfigurable dynamical logic gate with linear core
(2008-10)
"A dynamically reconfigurable linear core logic gate is a device that allows logical outputs dependent upon configurable parameters set within device. The device is comprised of three blocks: The first block receives at ...
Comparing performance on chaos control via adaptive output-feedback
(2006)
"Performance of four controllers is experimentally compared and evaluated in context of chaos suppression. Four output-feedback controllers are used in experi- ments for comparison. First three schemes utilize an adaptive ...
Make a PI controller on an 8-bit micro
(2006-01)
"This article shows you how to implement a classical PI (proportional-integral) controller on a simple 8-bit microcontroller. To implement the PI controller, we developed specific libraries that make it possible for the ...
Feedback induction of limit cycle in a bioreactor: controlling towards scale-down
(2004)
"The feedback stabilization of periodic orbits (induction of limit cycle) via PI-like control is proposed as plausible tool for scale-down studies. An isothermal continuous stirred tank bioreactor (CSTB), with nonideal ...
A standard microcontroller based Discrete-Time PI for controlling the motion of a DC-Gearmotor
(2005-05)
"This paper shows how the INTEL© D8751 H microcontroller can be used to control the motion of a DC-Gearmotor. One advantage of this design is that does not require external memory RAM/EPROM to perform the control of the ...
