Comparación técnica de la operatividad entre los servicios de control de tráfico aéreo y marítimo, a fin de identificar las ventajas y disfunciones de cada uno y de ambos conjuntamente. <br/>Analizar las interacciones que ...
1.1 Objectius de la tesi.<br/>En els últims anys el control del parell i de la velocitat del motor d'inducció ha estat llargament estudiat. Un cop s'ha considerat que les prestacions dinàmiques assolibles eren ja suficientment ...
In this PhD thesis a methodology for the quality control of reinforced fiberglass plastic manufacturing process is proposed. The system is based on the ultrasonic pulse-echo nondestructive method and longitudinal waves on ...
Tradicionalmente, el diseño de sistemas de control en convertidores conmutados DC/DC se ha realizado mediante técnica de modulación de anchura de pulsos (PWM); sin embargo, la utilización de la teoría de sistemas de ...
El sistema de acondicionamiento de potencia es clave para el funcionamiento correcto del resto de sistemas eléctricos de un satélite. Los reguladores conmutados continua - continua son las piezas que enlazan los paneles ...
El treball parteix de la idea que l'arquitectura és essencialment geomètrica i vol demostrar que el coneixement de la geometria és imprescindible per a arribar a fer una obra d'arquitectura.<br/>S'estudien uns 30 exemples ...
The SDN (Software-Defined Networks) architecture separates the data and the control planes of the networks. It logically centralizes the control of a network in a central point that is an SDN controller, which acts as a ...
El control de convertidores de potencia conmutados CC/CC es un área de investigación muy activa tanto en electrónica de potencia como en teoría de control automático. Debido esencialmente, a la actual demanda de este tipo ...
The installation of power generation systems based on renewable energy sources has been increasing exponentially over the last decades. However, in spite of the well-known merits of such energy sources, the expansion of ...
The present doctoral thesis focuses on designing control schemes for three-phase three-wire voltage-sourced inverters connected to the grid under voltage disturbances. The research recognizes the large-scale integration ...
Un tema central en la ciencia y la tecnología es la exploración y explotación de sistemas cada vez más pequeños por medio de técnicas ópticas. A menudo, la longitud de onda viene dictada por el sistema de interés: los ...
Power system is undergoing an unpreceded paradigm shift: from centralized to distributed generation. As the renewable-based generations and battery storage systems are increasingly displacing conventional generations, it ...
The present PhD thesis analyzes the modelling and control of the two main topologies of large scale variable speed wind turbines, the doubly fed induction generator and the permanent magnet synchronous generator wind ...
Microgrids are the near future candidate to reduce the dependence on the carbon-based generation, towards a more environmentally friendly and sustainable energy paradigm. The popularization of the use of renewable energy ...
(English) The control strategies implemented in exoskeletons play a crucial role in determining the interaction between the device and user. However, it is unclear what is the most suitable control strategy and settings ...
(Enlish) In the past years, battery electric vehicles have been gaining market share. These vehicles are progressively seen as a viable option by customers of all kind. However, although manufacturers and research institutions ...
Distributed Generation (DG) provides an alternative to the Centralized Generation (CG) by means of generating electricity near to the end user of power with the employment of small-scale technologies to produce electricity, ...
Aquesta tesi presenta treball original i aplicat en l'àrea del control i la col·locació de sensors/actuadors (S/A) en sistemes de Control Actiu de Soroll (ANC). Primer, s'han aplicat tècniques de control i identificació ...
The multiphase synchronous buck converter is universally used today for powering low voltage, high current and high slew-rate loads, such as CPUs and other high performance digital ICs. This converter demands control ...
The last decades have witnessed impressive technical advances in all the fields of quantum science, including solid-state systems or atomic, molecular, and optical physics, allowing one to control materials at the microscopic ...
