Sliding mode control of a dc-dc dual active bridge using the generalized space-state averaging description
(2021)
Conference report
Open AccessThis paper presents a sliding mode control strategy for a dc-dc dual active bridge converter. The controller is based on a truncated model obtained using the generalized state space averaging method that transforms the ... -
Contributions to the pendulum-type wave energy converter system for oceanic drifter applications
(2021)
Conference report
Open AccessLagrangian Drifters are autonomous floating passive devices that provide oceanographic surface data. They are low-cost, versatile and easy-deployable marine instrumentation used in climate research. One of the main challenges ... -
Nonlinear dynamic analysis of pendulum-type Wave Energy Converter for low-power marine monitoring applications
(European Wave and Tidal Energy Conference (EWTEC), 2021)
Conference report
Open AccessA model for a double pendulum Wave Energy Converter (WEC) for drifter applications has been developed and validated. The WEC is composed by an articulated arm, a gear train, a flywheel, a one-way bearing and a DC generator. ... -
High-frequency spread-spectrum modulations for wide-bandgap voltage source converters
(Institute of Electrical and Electronics Engineers (IEEE), 2021)
Conference lecture
Restricted access - publisher's policyThe high efficiency and the electromagnetic com- patibility of wide-bandgap (WBG) power converters can be further improved using spread-spectrum (SS) modulations. This paper evaluates and compares the impact of SS techniques ... -
Miniaturised bidirectional acoustic tag to enhance marine animal tracking studies
(Institute of Electrical and Electronics Engineers (IEEE), 2021)
Conference report
Restricted access - publisher's policyAcoustic underwater tags are key devices to study marine animals and comprehend their patterns, which provide essential behavioural information for applying new conservation policies. At present, all the acoustic tags have ... -
Analysis and initial design of bidirectional acoustic tag modulation schemes and communication protocol
(2021)
Conference report
Restricted access - publisher's policyAcoustic underwater tags are key devices to study marine animals and obtain information regarding their behaviour. This information is essential to increase our knowledge of oceanic species and implement efficient conservation ... -
Real-time wave monitoring on coastal areas using LPWAN-based embedded systems
(2021)
Conference report
Restricted access - publisher's policyA new embedded system is presented for real-time wave monitoring on coastal areas using SigFox communication. SigFox is a Low-Power Wide-Area Network technology that has been rarely used in coastal marine monitoring. The ... -
An interoperable architecture for in situ ocean noise monitoring
(2021)
Conference report
Open AccessAnthropogenic noise in the oceans has been significantly raising in the past decades due to an increment of human activities, adversely affecting the marine habitat. In order to assess and limit this impact, the long -term ... -
An integrated biogeochemistry observation system at Besòs estuary
(2021)
Conference report
Open AccessEstuaries are coastal indentations where freshwater mixes with seawater (Pritchard 1967), and are found everywhere in the world. Moreover, the estuarine ecosystems are usually characterized by high biological productivity ... -
Developing an acoustic tag with bidirectional communications capabilities
(2021)
Conference report
Open AccessThe study of marine animal behaviour is crucial to manage fisheries stocks and to understand the climate change effect on them, especially their moving patterns. In order to achieve that, different methods have been developed ... -
Underwater light estimation using the OBSEA camera
(2021)
Conference report
Open AccessThis is a description of the method used in the OBSEA observatory to obtain a value for the amount of light present in the seafloor using the existing video surveillance camera. -
Evaluation of two MPPT techniques in low-power pendulum-type wave energy converters
(2021)
Conference report
Open AccessTwo Maximum Power Point Tracking (MPPT) techniques have been tested on a Power Management Unit (PMU) which efficiently controls the generated energy of a Kinetic Energy Harvester (KEH) for drifter applications. Tests have ...
