A Data Dropout Compensation Algorithm Based on the Iterative Learning Control Methodology for Discrete-Time Systems
(Hindawi Publishing Corporation, 2015)
This paper deals with the convergence of a remote iterative learning control system subject to data dropouts. The system is composed by a set of discrete-time multiple input-multiple output linear models, each one with its ...
Influence of Humidity on Fiber Bragg Grating Sensors
(Hindawi, 2014-01)
We demonstrate the influence of the relative humidity (RH) on the wavelength of fiber Bragg grating sensors (FBGS), performing tests with five FBGS at different humidity and temperature conditions. These tests were performed ...
Performance of an Ocean Energy Conversion System with DFIG Sensorless Control
(Hindawi Publishing Corporation, 2013-05)
The 2009/28/EC Directive requires Member States of the European Union to adopt a National Action Plan for Renewable Energy. In this context, the Basque Energy Board, EVE, is committed to research activities such as the ...
Framework for the Shape Optimization of Aerodynamic Profiles Using Genetic Algorithms
(Hindawi Publishing Corporation, 2013)
This study developed a framework for the shape optimization of aerodynamics profiles using computational fluid dynamics (CFD) and genetic algorithms. Agenetic algorithm code and a commercial CFD code were integrated to ...
Effective and Robust Generalized Predictive Speed Control of Induction Motor
(Hindawi Publishing Corporation, 2013-10-16)
This paper presents and validates a new proposal for effective speed vector control of induction motors based on linear Generalized Predictive Control (GPC) law. The presented GPC-PI cascade configuration simplifies the ...
SEM and EDS Characterisation of Layering TiOx Growth onto the Cutting Tool Surface in Hard Drilling Processes of Ti-Al-V Alloys
(Hindawi Publishing Corporation, 2011)
Scanning electron microscopy (SEM) has been used to identify and analyse the secondary adhesion effect precursors formed during
the dry drilling processes of Ti-6Al-4V alloy over the rake face and flute of the drilling ...
Low Effort L-i Nuclear Fusion Plasma Control Using Model Predictive Control Laws
(Hindawi Publishing, 2015)
One of the main problems of fusion energy is to achieve longer pulse duration by avoiding the premature reaction decay due to plasma instabilities. The control of the plasma inductance arises as an essential tool for the ...
Suboptimal regulation of a class of bilinear interconnected systems with finite-time sliding planning horizons
(Hindawi Publishing Corporation, 2008)
This paper focuses on the suboptimization of a class of multivariable discrete-time bilinear systems consisting of interconnected bilinear subsystems with respect to a linear quadratic optimal regulation criterion which ...
Robust Sliding Mode Control for Tokamaks
(Hindawi Publishing Corporation, 2012)
Nuclear fusion has arisen as an alternative energy to avoid carbon dioxide emissions, being the tokamak a promising nuclear fusion reactor that uses a magnetic field to confine plasma in the shape of a torus. However, ...
