  • 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 ...

  • Comprehensive high speed automotive SM-PMSM torque control stability analysis including novel control approach 

    Arias Pujol, Antoni; Ibarra Basabe, Edorta; Trancho, Elena; Griñó Cubero, Robert; Kortabarria, Iñigo; Caum Aregay, Jesús (2019-07-01)
    Article
    Restricted access - publisher's policy
    Permanent magnet synchronous machines (PMSM) are widely used in the automotive industry for electric vehicle (EV) and hybrid electric vehicle (HEV) propulsion systems, where the trend is to achieve high mechanical speeds. ...

  • Robust admittance shaping approach to grid current harmonic attenuation and resonance damping 

    Cóbreces Álvarez, Santiago; Wang, Xiongfei; Pérez Serrano, Jorge; Griñó Cubero, Robert; Blaabjerg, Frede (2018-09-01)
    Article
    Open Access
    This paper presents a novel grid current control of a grid-connected voltage source converter with an LCL filter. The proposed control method uses an H 8 synthesis method to shape the input admittance of the converter, to ...

  • Complex-based controller for a three-phase inverter with an LCL filter connected to unbalanced grids 

    Dòria Cerezo, Arnau; Martin Serra, Federico; Bodson, Marc (Institute of Electrical and Electronics Engineers (IEEE), 2018-07-09)
    Article
    Open Access
    A new controller for a grid connected inverter with an LCL filter is proposed in this paper. The system is described by its complex representation and the controller is designed using the complex root locus method. The ...
