Publicación Comparison of the vertical dynamic models of a fast ferry with actuators and without actuators(3rd. International Congress on Marine Technological Innovations and Research, 2002-11-06) Aranda Almansa, Joaquín; Díaz Martínez, José Manuel; Muñoz Mansilla, María del RocíoPublicación Design of a low-cost air levitation system for teaching control engineering(MDPI, 2017-10-12) Chacón, Jesús; Sáenz Valiente, Jacobo; Torre Cubillo, Luis de la; Díaz Martínez, José Manuel; Esquembre, FranciscoAir levitation is the process by which an object is lifted without mechanical support in a stable position, by providing an upward force that counteracts the gravitational force exerted on the object. This work presents a low-cost lab implementation of an air levitation system, based on open solutions. The rapid dynamics makes it especially suitable for a control remote lab. Due to the system’s nature, the design can be optimized and, with some precision trade-off, kept affordable both in cost and construction effort. It was designed to be easily adopted to be used as both a remote lab and as a hands-on lab.Publicación Evidence-Based Control Engineering Education: Evaluating the LCSD Simulation Tool(IEEE, 2020-09-25) Marin, Loreto; Vargas, Héctor; Heradio Gil, Rubén; Torre Cubillo, Luis de la; Díaz Martínez, José Manuel; Dormido Canto, SebastiánThe advance in control engineering education needs well-designed studies that validate what methods and tools work best. This paper addresses the lack of empirical evidence supporting innovations in control engineering education by proposing a methodology that works at different abstraction levels. Hence, innovations' impact on students' performance can be statistically analyzed either globally or locally by examining competencies or fine-grained indicators, respectively. The article reports the application of the methodology for evaluating an interactive simulation tool, named LCSD, on 101 students at the Pontifical Catholic University of Valparaiso in Chile. According to the experimental results, LCSD is an effective free alternative to enhance the student's skills on control system analysis for our automatic control course. Also, some improvements have been identified for future LCSD versions.Publicación Control problems in marine vehicles: Some experiences in stabilization and tracking control(2006-01-01) Cruz García, Jesús Manuel de la; Riola Rodríguez, José María; Aranda Almansa, Joaquín; Muñoz Mansilla, María del Rocío; Chaos García, Dictino; Díaz Martínez, José Manuel; Dormido Canto, SebastiánPublicación Interactive software tools for robust control: application to marine systems(Robotics and Automation in the Maritime Industries, 2006-01-01) Dormido Bencomo, Sebastián; Díaz Martínez, José Manuel; Aranda Almansa, Joaquín; Dormido Canto, Sebastián; Muñoz Mansilla, María del Rocío; Chaos García, DictinoPublicación Disminucion del indice de mareo mediante un control pd sobre el movimiento de arfada y el angulo de cabeceo en un buque de alta velocidad(Comité Español de Automática, 2000-09-18) Cruz García, Jesús Manuel de la; Aranda Almansa, Joaquín; Díaz Martínez, José Manuel; Ruipérez García, PabloPublicación ENTORNO DE SIMULACIÓN INTERACTIVA PARA EL CONTROL(2007-11-13) Aranda Almansa, Joaquín; Dormido Canto, Sebastián; Muñoz Mansilla, María del Rocío; Chaos García, Dictino; Díaz Martínez, José ManuelPublicación An analysisof models identification methods for high speed crafts(Journal of Maritime Research, 2005-01-01) Dormido Bencomo, Sebastián; Aranda Almansa, Joaquín; Muñoz Mansilla, María del Rocío; Dormido Canto, Sebastián; Díaz Martínez, José ManuelTwo different approaches of the system identification method have been proposed in order to estimate models for heave, pitch and roll dynamics of a high speed craft. Both of them resolve the identification subject as an optimization problem to fit the best model. The first approach uses genetic algorithms and nonlinear least squares with constraints methods applied in the frequency domain. The second one suggests a new parameterization which facilitates obtaining high quality starting values and avoids non-quadratic functions in the cost function. At last it is shown an example in which the two approximations are applied and compared.Publicación Interactive computer-aided control design using quantitative feedback theory: the problem of vertical movement stabilization on a high-speed ferry(Taylor and Francis, 2005-07-20) Dormido Bencomo, Sebastián; Díaz Martínez, José Manuel; Aranda Almansa, JoaquínIn a first approximation, the vertical acceleration associated with pitch motion can be considered as the main cause of motion sickness, which is without a doubt one of the most unpleasant disadvantages of maritime transport. The reduction of motion sickness can be stated as a monovariable regulation problem of a highly perturbed system. This work presents the design of a monovariable robust controller with quantitative feedback theory (QFT) for reducing the vertical movement on a high-speed ferry. The different stages of QFT methodology have been done with the help of the software tool QFTIT (Quantitative Feedback Theory Interactive Tool). This is a free software tool that is characterized by its ease of use and interactive nature. The designed regulator is validated experimentally in sea behaviour trials with a scaled down replica 1/25 the size of a high-speed ferry. The designed regulator is also compared with a gain-scheduling scheme using a proportional and derivative controller (PD).Publicación Identification for robust control of a fast ferry(University of Navarre, 2001-08-23) Cruz García, Jesús Manuel de la; Aranda Almansa, Joaquín; Díaz Martínez, José Manuel; Ruipérez García, Pablo
