    This contribution evaluates an approach using an extended Kalman filter (EKF) to estimate the planetary boundary layer height (PBLH) from lidar measurements obtained in the framework of the European Aerosol Research LIdar ...
  • Sliding-mode control for a three-phase shunt active power filter in natural frame 

    Guzmán Solà, Ramon; García de Vicuña Muñoz de la Nava, José Luis; Morales López, Javier; Castilla Fernández, Miguel; Miret Tomàs, Jaume; Torres Martínez, Javier (2015)

    This paper presents an improved variable hysteresis-band current-control in natural frame for a three-phase shunt active power filter. The proposed control algorithm is based on three decoupled sliding-mode controllers ...
  • Synergetic use of lidar and microwave radiometer observations for boundary-layer height detection 

    Saeed, Umar; Rocadenbosch Burillo, Francisco; Crewell, Susanne (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Conference report
    Restricted access - publisher's policy
    A synergetic approach for estimation of the nocturnal stable boundarylayer (SBL) height is presented. Aerosol backscatter from a lidar ceilometer and potential temperature from a microwave radiometer (MWR) are combined ...
  • The formulation of structural time series models in discrete and continuous time 

    Harvey, A. C. (Universitat Politècnica de Barcelona. Centre de Càlcul, 1983-12)
    Open Access
    This paper sets out an approach for modelling univariate time series, including those in which observations are available on a daily basis. An underlying continuous time model is formulated and it is shown that this model ...
  • Vision-based absolute navigation for the Martian landing 

    Martínez Torío, Alexandra (Universitat Politècnica de Catalunya, 2013-12-09)
    Master thesis
    Restricted access - author's decision
    Future European missions aspire to bring soil samples from Mars back to Earth. The precise identification of the site from which samples are taken leads to major constraints as to the landing accuracy of the lander. ...
