    Flexibility and reliability of AC microgrids are enhanced by reducing the dependence on communications in multi-layer hierarchical control. In this sense, this paper presents a secondary control with no communications for ...
  • Variable structure control for three-phase LCL-filtered inverters using a reduced converter model 

    Guzmán Solà, Ramon; García de Vicuña Muñoz de la Nava, José Luis; Castilla Fernández, Miguel; Miret Tomàs, Jaume; Hoz Casas, Jordi de la (Institute of Electrical and Electronics Engineers (IEEE), 2017-06-16)
    Article
    Accés obert
    This paper presents a new concept in active damping techniques using a reduced model of a LCL-filtered grid connected inverter. The presence of the LCL filter complicates the design of the inverter control scheme, particularly ...
  • Variable structure control in natural frame for three-phase grid-connected inverters with LCL filter 

    Guzmán Solà, Ramon; García de Vicuña Muñoz de la Nava, José Luis; Castilla Fernández, Miguel; Miret Tomàs, Jaume; Martín Cañadas, María Elena (2017-07-05)
    Article
    Accés obert
    This paper presents a variable structure control in natural frame for a three-phase voltage source inverter. The proposed control method is based on modifying the converter model in natural reference frame, preserving the ...
  • Baitmet, a computational approach for GC–MS library-driven metabolite profiling 

    Domingo, Xavier; Brezmes, Jesus; Venturini, G; Vivó-Truyols, Gabriel; Perera Lluna, Alexandre; Vinaixa, Maria (2017-06-24)
    Article
    Accés restringit per política de l'editorial
    Current computational tools for gas chromatography – mass spectrometry (GC – MS) metabolomics profiling do not focus on metabolite identification, that still remains as the entire workflow bottleneck and it relies on manual ...
  • Task-dependent synergies for motion planning of an anthropomorphic dual-arm system
