Recent Submissions

  • Space-time Schrödinger symmetries of a post-Galilean particle 

    Batlle Arnau, Carles; Gomis Torné, Joaquin (Springer, 2020-08-07)
    Article
    Open Access
    We study the space-time symmetries of the actions obtained by expanding the action for a massive free relativistic particle around the Galilean action [1]. We obtain all the point space-time symmetries of the post-Galilean ...
  • A simple switching frequency regulated sliding mode controller for a VSI with a full digital implementation 

    Repecho del Corral, Víctor; Biel Solé, Domingo; Olm Miras, Josep Maria (Institute of Electrical and Electronics Engineers (IEEE), 2020-01-06)
    Article
    Open Access
    This paper describes the design of a first order sliding mode controller for a VSI operating at fixed switching frequency. The proposal is simple, as it does not include any integral or resonant action in the switching ...
  • Open loop testing for optimizing the closed loop operation of chemical systems 

    Domínguez Pumar, Manuel; Olm Miras, Josep Maria; Kowalski, Lukasz; Jiménez Serres, Vicente (Pergamon Press, 2020-04-06)
    Article
    Restricted access - publisher's policy
    One way to optimize the operation of chemical systems consists on using closed loop controls while the system is operated. This way, it is possible to optimize the operating point in the plant, process or chemical system ...
  • A comparative study of terminal and conventional sliding mode start-up peak current controls for a synchronous buck converter 

    Repecho del Corral, Víctor; Masclans, Nuria; Biel Solé, Domingo (Institute of Electrical and Electronics Engineers (IEEE), 2019-08-20)
    Article
    Open Access
    An alternative to the linear control techniques, which are based on small signal averaged models, is the sliding mode control. That method uses instantaneous models of the switched power converter to design robust controllers. ...
  • A sensor-less sliding mode control scheme for a stand-alone wound rotor synchronous generator under unbalanced load conditions 

    Muñoz Aguilar, Raúl Santiago; Rodríguez Cortés, Pedro; Dòria Cerezo, Arnau; Candela García, José Ignacio; Luna Alloza, Álvaro (2004-09)
    Article
    Restricted access - publisher's policy
    This paper presents a sliding mode control for a wound rotor synchronous machine acting as an isolated generator connected to an unbalanced load. In order to simplify the control methodology, the standard dq-model of the ...
  • Feedback linearizing control of a magnetically coupled multiport dc-dc converter for automotive applications 

    Olm Miras, Josep Maria; Fossas Colet, Enric; Repecho del Corral, Víctor; Dòria Cerezo, Arnau; Griñó Cubero, Robert (2019)
    Conference report
    Open Access
    This paper presents a feedback linearization-based control strategy for a a magnetically coupled multiport dc-dc converter aimed at automotive applications. Essentially, a transformation of control and state variables is ...
  • Active damping of a DC network with a constant power load: an adaptive observer-based design 

    Machado, Juan; Ortega, Romeo; Astolfi, Alessandro; Arocas Pérez, José; Pyrkin, Anton; Bobtsov, Alexey; Griñó Cubero, Robert (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference report
    Open Access
    This paper proposes a nonlinear, output feedback, adaptive controller to increase the stability margin of a direct-current (DC), small-scale, electrical network containing an unknown constant power load. Due to their ...
  • Application of sliding-mode control to the design of a buck-based sinusoidal generator 

    Biel Solé, Domingo; Fossas Colet, Enric; Guinjoan Gispert, Francisco; Alarcón Cot, Eduardo José; Poveda López, Alberto (Institute of Electrical and Electronics Engineers (IEEE), 2001-06)
    Article
    Open Access
    This paper is devoted to the design of a sliding-mode control scheme for a buck-based inverter, with programmable amplitude, frequency, and DC offset, with no external sinusoidal reference required. A general procedure for ...
  • A relay controller with parallel feed-forward compensation for a buck converter feeding constant power loads 

    Rafiezadeh, Roya; Griñó Cubero, Robert (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference report
    Open Access
    A simple and efficient analog direct voltage control design for improving the performance and stability of a buck converter feeding constant power loads (CPLs) is the main aim of this article. One of the oldest and most ...
  • Modelling and simulation of a magnetically coupled multiport dc-dc converter 

    Griñó Cubero, Robert; Dòria Cerezo, Arnau (2019)
    Conference report
    Open Access
    This paper present two different approaches for modelling a magnetically coupled multiport dc-dc converter. First, from the magnetic coupling equations, the instantaneous dynamic model is obtained. Secondly, a behavioural ...
  • A black-box model for neurons 

    Roqueiro, Nestor; Claumann, Carlos; Guillamon Grabolosa, Antoni; Fossas Colet, Enric (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference lecture
    Open Access
    We explore the identification of neuronal voltage traces by artificial neural networks based on wavelets (Wavenet). More precisely, we apply a modification in the representation of dynamical systems by Wavenet which decreases ...

    Machado, Juan E.; Arocas Pérez, José; He, Wei; Ortega, Romeo; Griñó Cubero, Robert (2018)
    Conference lecture
    Open Access
    This paper proposes a nonlinear, adaptive controller to increase the stability margin of a direct-current (DC) small-scale electrical network containing a constant power load, whose value is unknown. Due to their negative ...
