  • Periodic nonlinear economic model predictive control with changing horizon for water distribution networks 

    Wang, Ye; Salvador, José Ramón; Muñoz De la Peña, David; Puig Cayuela, Vicenç; Cembrano Gennari, Gabriela (2017)
    Text en actes de congrés
    Accés obert
    A periodic nonlinear economic model predictive control (EMPC) with changing prediction horizon is proposed for the optimal management of water distribution networks (WDNs). The control model of the WDN is built by means ...
  • Economic model predictive control for energy dispatch of a smart micro-grid system 

    Nassourou, M; Puig Cayuela, Vicenç; Blesa Izquierdo, Joaquim; Ocampo-Martínez, Carlos (2017)
    Text en actes de congrés
    Accés obert
    The problem of energy dispatch in heterogeneous complex systems such as smart grids cannot be efficiently solved using classical control or ad-hoc methods. This paper proposes the application of Economic Model Predictive ...
  • Identification of PEM fuel cells based on support vector regression and orthonormal bases 

    Feroldi, Diego Hernan; Gómez, Juan Carlos; Roda Serrat, Vicente (2016)
    Text en actes de congrés
    Accés obert
    Polymer Electrolyte Membrane Fuel Cells (PEMFC) are efficient devices that convert the chemical energy of the reactants in electricity. In this type of fuel cells, the performance of the air supply system is fundamental ...
  • Parallax angle parametrization in incremental SLAM 

    Paiva Mendes, Ellon; Lacroix, Simon; Solà Ortega, Joan (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Text en actes de congrés
    Accés obert
    The lack of depth information in camera images has triggered much work on their use for localization and mapping in robotics. In particular, specific landmark parametrizations that isolate the unknown depth in one variable, ...
  • Different architectures to develop repetitive controllers 

    Sanz i López, Víctor; Costa Castelló, Ramon; Ramos Fuentes, German A. (2017)
    Text en actes de congrés
    Accés obert
    In this work several architectures to implement repetitive controllers are compared. A complete analytical analysis is performed for these dierent architectures and a simulation example with a power converter is included.
  • Reduced-order interval-observer design for dynamic systems with time-invariant uncertainty 

    Pourasgharlafmejani, Masoud; Puig Cayuela, Vicenç; Ocampo-Martínez, Carlos; Zhang, Qinghua (2017)
    Text en actes de congrés
    Accés obert
    This paper addresses the design of reduced-order interval-observers for dynamic systems with time-invariant uncertainty. Because of the limitations of using the set-based approach to preserve the time dependency of parameter ...
  • Planning clearing actions in cluttered scenes by phasing in geometrical constraints 

    Covallero, Nicola; Martinez Martinez, David; Alenyà Ribas, Guillem; Torras, Carme (IOS Press, 2017)
    Text en actes de congrés
    Accés obert
    Manipulation planning of cluttered objects involves a mixture of symbolic and geometric constraints which makes such planning very time consuming and often unsuitable for real applications. We propose to divide the geometric ...
  • Observer-based sensor fault detectability: about robust positive invariance approach and residual sensitivity 

    Rahman Kodakkadan, Abid; Pourasgharlafmejani, Masoud; Puig Cayuela, Vicenç; Olaru, Sorin; Ocampo-Martínez, Carlos; Reppa, Vasso (2017)
    Text en actes de congrés
    Accés obert
    This paper considers detectability of deviation of sensors from their nominal behavior for a class of linear time-invariant discrete-time systems in the presence of bounded additive uncertainties. Detectable sensor faults ...
  • Closure polynomials for strips of tetrahedra 

    Thomas, Federico; Porta Pleite, Josep Maria (Springer, 2016)
    Text en actes de congrés
    Accés obert
    A tetrahedral strip is a tetrahedron-tetrahedron truss where any tetrahedron has two neighbors except those in the extremes which have only one. Unless any of the tetrahedra degenerate, such a truss is rigid. In this case, ...
  • Combined heat and power using high temperature proton exchange membrane fuel cells for comfort applications 

    Sanz i López, Víctor; Costa Castelló, Ramon; Batlle Arnau, Carles (2017)
    Text en actes de congrés
    Accés obert
    Global concerns about nowadays’ energy shortage problems as well as climate change eects have encouraged alternatives to classical energy sources such as fossil fuels and nuclear power plants. In this context, combined ...
  • PL-SLAM: real-time monocular visual SLAM with points and lines 

    Pumarola Peris, Albert; Vakhitov, A.; Agudo Martínez, Antonio; Sanfeliu Cortés, Alberto; Moreno-Noguer, Francesc (IEEE Press, 2017)
    Text en actes de congrés
    Accés obert
    Low textured scenes are well known to be one of the main Achilles heels of geometric computer vision algorithms relying on point correspondences, and in particular for visual SLAM. Yet, there are many environments in which, ...
  • Global model with local interpretation for dynamic shape reconstruction 

    Agudo Martínez, Antonio; Moreno-Noguer, Francesc (2017)
    Text en actes de congrés
    Accés obert
    The most standard approach to resolve the inherent ambiguities of the non-rigid structure from motion problem is using low-rank models that approximate deforming shapes by a linear combination of rigid basis. These models ...
