  • Ageing of an oscillator due to frequency switching 

    Bonet Revés, Carles; Jeffrey, Mike R.; Martín de la Torre, Pablo; Olm Miras, Josep Maria (2021-11-01)

    If an oscillator is driven by a force that switches between two frequencies, the dynamics it exhibits depends on the precise manner of switching. Here we take a one-dimensional oscillator and consider scenarios in which ...
  • Enhanced DC-link voltage utilization for sliding mode controlled PMSM drives 

    Repecho del Corral, Víctor; Sierra González, Andrés; Ibarra Basabe, Edorta; Biel Solé, Domingo; Arias Pujol, Antoni (Institute of Electrical and Electronics Engineers (IEEE), 2021)
    Article
    Open Access
    Sliding mode control (SMC) can be considered for torque regulation of permanent magnet synchronous machines (PMSMs) when fast transient response and/or robustness under parameter uncertainties are required. In some particular ...
  • Modelling and nonlinear control of a magnetically coupled multiport DC-DC converter for automotive applications 

    Repecho del Corral, Víctor; Olm Miras, Josep Maria; Griñó Cubero, Robert; Dòria Cerezo, Arnau; Fossas Colet, Enric (Institute of Electrical and Electronics Engineers (IEEE), 2021-04-21)
    Article
    Open Access
    This work presents a nonlinear control strategy for a magnetically coupled multiport dc-dc converter aimed at automotive applications. First, a behavioural dynamic model, based on averaging the power flowing among the ...
  • Multicellular feedback control of a genetic toggle-switch in microbial consortia 

    Fiore, Davide; Salzano, Davide; Cristòbal-Cóppulo, Enric; Olm Miras, Josep Maria; di Bernardo, Mario (2021-01)
    Article
    Open Access
    We describe a multicellular approach to control a target cell population endowed with a bistable toggle-switch. The idea is to engineer a synthetic microbial consortium consisting of three different cell populations. In ...
  • Novel thermal management strategy for improved inverter reliability in electric vehicles 

    Trancho, Elena; Ibarra Basabe, Edorta; Prieto, Pablo; Arias Pujol, Antoni; Lis, Adrian; Pai, Ajay Poonjal (MDPI, 2020-11-12)
    Article
    Open Access
    Requirements for electric vehicle (EV) propulsion systems—i.e., power density, switching frequency and cost—are becoming more stringent, while high reliability also needs to be ensured to maximize a vehicle’s life-cycle. ...
  • A canonical realization of the Weyl BMS symmetry 

    Batlle Arnau, Carles; Campello Román, Víctor Manuel; Gomis Torné, Joaquim (Elsevier, 2020-12-10)
    Article
    Open Access
  • 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 ...
  • 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 ...
