“…On the other hand, the standard design procedures and some of the modeling and simulation tools for offshore structures come from existing technology and the experience of the offshore oil and gas extraction industry. Some of the programs used focus only on a particular part of the turbine, such as SeaFEM for the hydrodynamic part [21], or DNV GL for the blades and for the mooring system [22]. Most are based on numerical simulation and require great computational power (OrcaFlex and COUPLE) [23].…”

Floating offshore wind turbines (FOWT) are designed to overcome some of the limitations of offshore bottom-fixed ones. The development of computational models to simulate the behavior of the structure and the turbine is key to understanding the wind energy system and demonstrating its feasibility. In this work, a general methodology for the identification of reduced dynamic models of barge-type FOWTs is presented. The method is described together with an example of the development of a dynamic model of a 5 MW floating offshore wind turbine. The novelty of the proposed identification methodology lies in the iterative loop relationship between the identification and validation processes. Diversified data sets are used to select the best-fitting identified parameters by cross evaluation of every set among all validating conditions. The data set is generated for different initial FOWT operating conditions. Indeed, an optimal initial condition for platform pitch was found to be far enough from the system at rest to allow the dynamics to be well characterized but not so far that the unmodeled system nonlinearities were so large that they affected significantly the accuracy of the model. The model has been successfully applied to structural control research to reduce fatigue on a barge-type FOWT.

“…Besides the possibility of using the hydrodynamic forces disposed in Adams as a source of disturbances, some disturbances can be modeled directly from the Simulink model. Figure 11 shows the Simulink model for an experiment where the oscillatory behavior of waves on surfing were sup-pose being additive disturbance to the propeller forces as in [19], [20]. The sine block in the Simulink model of Figure 11 was dispose for this end.…”

This article presents a virtual environment based on co-simulation between MatLab and MSC Adams, allowing simulation, analysis, development and validation of control strategies for tracking of position trajectories of a Remotely Operated Vehicle (ROV). The simulation results in the horizontal plane show that it is possible, in an uncomplicated way, to construct a virtual environment, which allows observing realistic movements when the forces exerted on an ROV are provided. Taking advantage of the properties of co-simulation, the experiences in this work show that this simulation strategy is very suitable for analysis purposes and control design, allowing researchers and professionals the wide use of control tools available in MATLAB for this end. In this work, a robust linear quadratic regulator (LQR) with integral action has been used to evaluate the performance of the proposed virtual environment for tracking of position trajectories. To validation purposes, widely used trajectories in naval study designs were employed such as the Zig -Zag shaped and the Circular shaped trajectories. Simulation results show that the integration of both, MatLab and MSC Adams, effectively addressees the problem of evaluation of performance of control strategies in the virtual environment. The presented approach allows gaining experience about the challenges of this kind of control problems, before dealing with the complex aspects of tuning in real experimental environments, avoiding losses and cost overruns for underwater robotics projects.

“…En un contexto global en el que, tanto el incremento del consumo de energía como, el empleo de fuentes de energías derivadas de combustibles fósiles, han provocado un aumento de la contaminación ambiental, con las consecuencias nocivas que ello implica (Schwartz, 1994). Esto ha producido una expansión en el aprovechamiento de energías renovables no contaminantes, especialmente la energía eólica (de la Portilla et al, 2017;Zuo and Liu, 2012). Comúnmente, se emplea fibra de carbono como material base para la fabricación de las palas de aerogenerador.…”

<p>Los avances tecnológicos en general, y en el ámbito de la industria en particular, conllevan el desarrollo y optimización de las actividades que en ella tienen lugar. Para alcanzar este objetivo, resulta de vital importancia detectar cualquier tipo de anomalía en su fase más incipiente, contribuyendo, entre otros, al ahorro energético y económico, y a una reducción del impacto ambiental. En un contexto en el que se fomenta la reducción de emisión de gases contaminantes, las energías alternativas, especialmente la energía eólica, juegan un papel crucial. En la fabricación de las palas de aerogenerador se recurre comúnmente a materiales de tipo bicomponente, obtenidos a través del mezclado de dos substancias primarias. En la presente investigación se evalúan distintas técnicas inteligentes de clasificación one-class para detectar anomalías en un sistema de mezclado para la obtención de materiales bicomponente empleados en la elaboración de palas de aerogenerador. Para lograr los modelos inteligentes que permitan la detección de anomalías, se han usado datos reales extraídos de una planta de mezclado en operación durante su correcto funcionamiento. Los clasificadores obtenidos para cada técnica son validados a través de anomalías generadas de manera artificial, obteniéndose resultados altamente satisfactorios.</p>
