Co-design of H∞ jump observers for event-based measurements over networks
(Taylor & Francis, 2015-07-27)
This work presents a strategy to minimise the network usage and the energy consumption of wireless battery-powered sensors in the observer problem over networks. The sensor nodes implement a periodic send-on-delta approach, ...
Positive-Net-Damping Stability Criterion in Grid-Connected VSC Systems
(Institute of Electrical and Electronics Engineers (IEEE), 2017-05)
Resonance instabilities in power systems can be assessed with the positive-net-damping stability criterion. This criterion is a review of the complex torque coefficients method but it does not provide the frequency of the ...
Stability and Performance Analysis in Two-Parameter Controllers for Weak Grid-Connected VSCs
(IEEE, Institute of Electrical and Electronics Engineers, 2023)
In this study, we conduct an analysis of power control in a Voltage Source Converter (VSC) connected to a Weak Grid (WG), focusing on the system's stability and performance. Our main objective is to predict the behaviour ...
A simple procedure for fault detectors design in SISO systems
(Elsevier, 2020-03)
In this work, we present a novel approach for fault detectors design and implementation in the case of actuator faults. Both the design and the implementation are focused on simplicity. The fault detector is based in an ...
Dimensionless Tuning Procedure of the Kalman Filter for State-Of-Charge Estimators
(IEEE, Institute of Electrical and Electronics Engineers, 2023)
This paper presents a solution to the challenging problem of estimating the state of charge (SOC) of batteries using a Kalman filter algorithm. The algorithm requires knowledge of the dynamical model and its parameters, ...
Optimized battery sizing for merchant solar PV capacity firming in different electricity markets
(IEEE, 2019-10-14)
This work analyses the minimum energy capacity requirements to be demanded to battery energy storage systems used in megawatt-range merchant solar PV plants to grant capacity firming. The operation of such a plant is ...
Modeling and enhanced control of hybrid full bridge–half bridge MMCs for HVDC grid studies
(MDPI, 2020-01-01)
Modular multilevel converters (MMCs) are expected to play an important role in future
high voltage direct current (HVDC) grids. Moreover, advanced MMC topologies may include various
submodule (SM) types. In this sense, ...

En este trabajo se presenta la integración de 4diac-FORTE y Factory IO mediante OPC-UA. Dicha integración permite verificar software de control desarrollado según la norma IEC 61499 y de esta forma validar de metodologías ...
Evaluation of the inflammatory responses to sol–gel coatingswith distinct biocompatibility levels
(John Wiley and SonsWileyWiley PeriodicalsSociety For Biomaterials (USA)Japanese Society for BiomaterialsAustralasian Society for BiomaterialsKorean Society for Biomaterials, 2021-02-20)
The immune system plays a crucial role in determining the implantation outcome, and macrophages are in the frontline of the inflammatory processes. Further, cellular oxidative stress resulting from the material recognition ...
Resintonización dinámica de controladores SSOD-PI para evitar ciclos límite causados por perturbaciones tipo rampa
(Servizo de Publicacións. Universidade da CoruñaComité Español de Automática, BarcelonaUniversidad de La Rioja, 2022)
Uno de los principales fenómenos a evitar en los sistemas con muestreo por umbrales fijos es la aparición de ciclos límite. Existe bibliografía sobre cómo evitarlos usando técnicas clásicas de análisis, sin embargo, dichos ...
