Vásquez Quintero, Juan Carlos (Date of defense: 2009-12-04)
Distributed generation of electric energy has become part of the current electric power system. In this context a new scenario is arising in which small energy sources make up a new supply system: The microgrid.<br/><br/>The ...
Sanz Estapé, Gerard (Date of defense: 2016-03-18)
The success in the application of any model-based methodology (e.g. design, control, supervision) highly depends on the availability of a well calibrated model. There is no best or unique solution for the calibration problem ...
Malo Barragán, Shane Leonardo (Date of defense: 2009-12-02)
Isolated electric energy generation systems are often needed to supply electric loads where the electrical network is not available. This could be caused due to geographic isolation, the necessity of load mobility, demanded ...
Rincón Charris, Amílcar Alejandro (Date of defense: 2015-04-24)
In recent years the detection and diagnosis of faults in devices and processes has been a field of research and development that has been addressed from multiple perspectives: control engineering, artificial intelligence ...
Luna Pacho, Julio Alberto (Date of defense: 2017-02-27)
Proton exchange membrane (PEM) fuel cells, which use hydrogen as fuel, provide high power densities while operating at lower temperatures, reducing the cost of materials and maintenance. PEM fuel cells are suitable for a ...
Xu, Feng (Date of defense: 2014-11-27)
The fault-tolerant capability is an important performance specification for most of technical systems. The examples showing its importance are some catastrophes in civil aviation. According to some official investigations, ...
Ramos Fuentes, Germán Andrés (Date of defense: 2012-09-12)
The tracking/rejection of periodic signals constitutes a wide field of research in the control theory and applications area and Repetitive Control has proven to be an efficient way to face this topic; however, in some ...
Nevot Cercós, Javier (Date of defense: 2000-03-17)
En la presente tesis se desarrolla un sistema de control de la mezcla de aire y gasolina en un motor alternativo de cuatro tiempos, basado en redes neuronales. Para que el catalizador logre un grado de depuración aceptable ...
Llusà Serra, Aleix (Date of defense: 2015-12-04)
Nowadays, it is possible to acquire a huge amount of data, mainly due to the fact that it is easy to build monitoring systems together with big sensor networks. However, data has to be managed accordingly, which is not so ...
Navarro López, Eva Maria (Date of defense: 2002-06-28)
El propósito de la presente tesis es el estudio de la disipatividad en sistemas no lineales discretos. Dicho trabajo de investigación presenta nuevas contribuciones en la teoría de control no lineal discreto basado en ...
Rojas, Nicolàs (Date of defense: 2012-06-20)
This thesis addresses the kinematic analysis of mechanisms, in particular, the position analysis of kinematic chains, or linkages, that is, mechanisms with rigid bodies (links) interconnected by kinematic pairs (joints). ...
Javalera Rincón, Valeria (Date of defense: 2016-04-07)
This thesis describes a methodology to deal with the interaction between MPC controllers in a distributed MPC architecture. This approach combines ideas from Distributed Artificial Intelligence (DAI) and Reinforcement ...
Villamizar Vergel, Michael Alejandro (Date of defense: 2012-09-18)
La visión por computador y más específicamente el reconocimiento de objetos han demostrado en los últimos años un impresionante progreso que ha llevado a la aparición de nuevas y útiles tecnologías que facilitan nuestras ...
Igelmo Ganzo, Manuel (Date of defense: 2016-01-28)
The first objective proposed in the research of this thesis was the select and develop a (preferably simple) model for graphs, thus, the results obtained through the model may be extrapolated to the modeled objects: graphs. ...
Fargas Marquès, Andreu (Date of defense: 2016-01-22)
Plenty of Micro-electro-mechanical Systems (MEMS) devices are actuated using electrostatic forces, and specially, parallel-plate actuators are extensively used, due to the simplicity of their design. Nevertheless, ...
Trulls Fortuny, Eduard (Date of defense: 2015-02-20)
Local features have become an essential tool in visual recognition. Much of the progress in computer vision over the past decade has built on simple, local representations such as SIFT or HOG. SIFT in particular shifted ...
Aguilar Castillo, Wilbert Geovanny (Date of defense: 2015-09-04)
Micro Aerial Vehicles (MAVs), a subset of Unmanned Aerial Vehicles (UAVs), also known as drones, are becoming popular for several applications and gaining interest due to advantages as manufacturing and maintenance cost, ...
Castillo Pérez, Esteban del (Date of defense: 2013-09-30)
Desde hace varias décadas los robots industriales han demostrado su eficiencia para tareas desarrolladas en entornos perfectamente conocidos. No obstante, surgen importantes complicaciones operativas en entornos limitadamente ...
Avilés Rivero, Angélica Ivone (Date of defense: 2017-05-18)
Estimating and understanding motion from an image sequence is a central topic in computer vision. The high interest in this topic is because we are living in a world where many events that occur in the environment are ...
García Esteban, Mauricio (Date of defense: 2001-03-16)
En este trabajo se presenta, por medio del procedimiento sistemático de selección, definición y adecuación de estrategias generales del control no--lineal, seis diferentes algoritmos propuestos que permiten efectuar el ...
