  • 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

    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 ...
  • 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 ...
  • Balanced model order reduction method for systems depending on a parameter 

    Batlle Arnau, Carles; Roqueiro, Nestor (2019)
    Article
    Open Access
    We provide an analytical framework for balanced realization model order reduction of linear control systems which depend on an unknown parameter. Besides recovering known results for the first order corrections, we obtain ...
  • Experimental validation of a continuous-time MCSI algorithm with bounded adaptive gains 

    Montanaro, Umberto; Costa Castelló, Ramon; Olm Miras, Josep Maria; Larco Barros, Ciro (2019-08-01)
    Article
    Restricted access - publisher's policy
    Model reference adaptive control algorithms with minimal controller synthesis have proven to be an effective solution to tame the behaviour of linear systems subject to unknown or time-varying parameters, unmodelled dynamics ...
  • Decoupled inputs sliding mode controllers for a fuel cell-supercapacitor module in hybrid generation applications 

    Moré, Jerónimo José; Puleston, Paul Federico; Fossas Colet, Enric; Kunusch, Cristian (Springer, 2019-01-01)
    Article
    Open Access
    The development of Multiple Input/Multiple Output (MIMO) sliding mode control setups for a fuel cell/supercapacitor module is presented in this paper. The main objective of the proposed controllers consists in simultaneously ...
  • Robust sliding mode control of a DC/DC Boost converter with switching frequency regulation 

    Repecho del Corral, Víctor; Biel Solé, Domingo; Olm Miras, Josep Maria; Fossas Colet, Enric (2018-01-01)
    Article
    Restricted access - publisher's policy
    This paper presents the design of a hysteresis band controller to regulate the switching frequency in a sliding mode controlled nonlinear Boost power converter. The proposed architecture relies on a piecewise linear modeling ...
  • Fixed-switching frequency interleaved sliding mode eight-phase synchronous buck converter 

    Repecho del Corral, Víctor; Biel Solé, Domingo; Ramos Lara, Rafael Ramón (Institute of Electrical and Electronics Engineers (IEEE), 2018-01-01)
    Article
    Open Access
    This paper describes the design of an interleaved sliding mode control for a multiphase synchronous buck converter, which inherits the properties of sliding mode control, operates with fixed switching frequency in the ...
  • Lie symmetries of nonrelativistic and relativistic motions 

    Batlle Arnau, Carles; Gomis Torné, Joaquin; Ray, Sourya; Zanelli, Jorge (American Physical Society (APS), 2019-03-15)
    Article
    Open Access
    We study the Lie symmetries of non-relativistic and relativistic higher order constant motions in d spatial dimensions, i.e. constant acceleration, constant rate-of-change -of-acceleration (constant jerk), and so on. In ...
