    The objective of this paper is to analyze the dynamics of heat flow in thermal structures working under constant temperature operation. This analysis is made using the tools of sliding mode controllers. The theory is ...
  • Model identification of time-varying diffusive systems 

    Atienza García, María Teresa; Kowalski, Lukasz; Gorreta Mariné, Sergio; Pons Nin, Joan; Jimenez Serres, Vicente; Domínguez Pumar, Manuel (2018)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    This paper presents a characterization method based on diffusive representation for a class of linear or nonlinear time-varying diffusive systems. The system variation with time may come as a result of the own actuation ...
  • Self-calibrating closed-loop circuit for configurable constant voltage thermal anemometers 

    Gorreta Mariné, Sergio; Barajas Ojeda, Enrique; Kowalski, Lukasz; Atienza García, María Teresa; Domínguez Pumar, Manuel; Jimenez Serres, Vicente (Institution of Electrical Engineers, 2015-09-17)
    Article
    Accés obert
    A new circuit is described which applies a configurable voltage across an RTD while the current flowing through it is measured with a current mirror. The circuit also allows working with voltages above the IC supply voltage ...
  • Sliding mode analysis applied to improve the dynamical response of a spherical 3D wind sensor for Mars atmosphere 

    Atienza García, María Teresa; Kowalski, Lukasz; Gorreta Mariné, Sergio; Jimenez Serres, Vicente; Castañer Muñoz, Luis María; Domínguez Pumar, Manuel (2017-11-01)
    Article
    Accés obert
    The objective of this paper is to show how the structure of a thermal wind anemometer can be tuned to ensure a fast response when the sensor works in closed loop configuration (constant temperature operation). If the thermal ...
  • Sliding mode control of heterogeneous systems 

    Domínguez Pumar, Manuel; Gorreta Mariné, Sergio; Atienza García, María Teresa; Blokhina, Elena; Pons Nin, Joan (2017-06-01)
    Capítol de llibre
    Accés restringit per política de l'editorial
    This paper establishes a link between closed-loop controls for heterogeneous systems and sliding mode controls. We demonstrate that sliding mode analysis matches with experimental results from dielectric charge controllers. ...
