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 ... -
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 ... -
Theory of vertically trasverse functions and their application to control of critical mechanical systems.
(2009)"En esta tesis se desarrolla y analiza una metodología teórica para atacar la estabilización práctica de configuraciones para sistemas de segundo orden descritos en grupos de Lie. En particular, esta clase de sistemas ... -
Reactive and harmonic compensation in power electronic systems using adaptive control.
(2009)"En este trabajo de tesis se proponen tres controladores basados en modelo matemático de tres sistemas electrónicos de potencia. Los modelos analizados consideran el caso general de voltaje de fuente y corriente de carga ... -
A dynamic parameter estimator to control chaos with distinct feedback schemes
(2009)"A dynamic strategy is proposed to estimate parameters of chaotic systems. The dynamic estimator of parameters can be used with diverse control functions; for example, those based on: (i) Lie algebra, (ii) backstepping, ... -
Computing non-fragile PI controllers for delay models of TCP/AQM networks
(2009)"This article focuses on the stabilisation problem of fluid-flow delay models of transmission control protocol/active queue management (TCP/AQM) networks by using a proportional-integral (PI) controller as AQM strategy. ... -
Conditions for synchronization and chaos in networks of β-cells
(2009)"The insulin producing and releasing pancreatic β-cells play a key role in glucose homeostasis. The proper function of these cells is characterized by a spiking-bursting activity in their membrane potential. It is known ... -
On the stability of AQM controllers supporting TCP flows
(2009)"In this chapter we address the local asymptotic stability of some AQM controllers supporting TCP flows. We first consider a PI controller as AQM strategy. The complete set of PI controllers that stabilizes the linearized ... -
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 ... -
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 ... -
Adaptive observers with persistency of excitation for synchronization of chaotic aystems
(2009)"We address the problem of master-slave synchronization of chaotic systems under parameter uncertainty and with partial measurements. Our approach is based on observer-design theory hence, we view the master dynamics as a ... -
Global trajectory tracking through static feedback for robot manipulators with bounded inputs
(2009)"In this work, two globally stabilizing bounded control schemes for the tracking control of robot manipulators with saturating inputs are proposed. They may be seen as extensions of the so-called PD+ algorithm to the bounded ... -
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 ... -
