    The success of any diagnosis strategy critically depends on the sensors measuring process variables. This paper presents a strategy based on diagnosability maximization for optimally locating sensors in distribution networks. ...
  • Quasi-LPV modelling and non-linear identification of a twin rotor system 

    Nejjari Akhi-Elarab, Fatiha; Rotondo, Damiano; Puig Cayuela, Vicenç; Innocenti, Mario (2012)
    Conference report

    This paper describes the experimental identifi- cation of the parameters of the Twin Rotor MIMO System (TRMS) non-linear model using data collected from the real lab set-up. From this non-linear model, ...
  • Fault estimation and virtual sensor FTC approach for LPV systems 

    Montes de Oca, Saúl; Rotondo, Damiano; Nejjari Akhi-Elarab, Fatiha; Puig Cayuela, Vicenç (Institute of Electrical and Electronics Engineers (IEEE), 2011)
    Conference report

    In this paper, a Fault Tolerant Control (FTC) strategy using a virtual sensor for Linear Parameter Varying (LPV) systems is proposed. The main idea of this FTC method is to reconfigure the control loop such that the nominal ...
  • Methodology for leakage isolation using pressure sensitivity analysis in water distribution networks 

    Pérez Magrané, Ramon; Puig Cayuela, Vicenç; Pascual Pañach, Josep; Quevedo Casín, Joseba Jokin; Landeros, E.; Peralta, Antoni (2011-07)
    Article

    This letter proposes a phase-shifted pulse-width modulation (PS-PWM) technique for the flying capacitor (FC) multilevel converter that improves the quality of the line-to-line voltages. In traditional PS-PWM, the line-to-line ...
  • Introduccion a la diagnosis de fallos basada en modelos mediante aprendizaje basado en proyectos 

    Costa Castelló, Ramon; Puig Cayuela, Vicenç; Blesa Izquierdo, Joaquim (2016-04-01)
    Article
    Open Access
    La diagnosis de fallos basada en modelos es hoy en día un campo maduro dentro de la ingeniería de control que empieza a formar parte de los planes de estudios de grado y postgrado. Sin embargo, la falta de buenos materiales ...
  • Evaluating the use of robots to enlarge AAL services 

    Angulo Bahón, Cecilio; Pfeiffer, Sammy; Alenyà Ribas, Guillem; Téllez Lara, Ricardo (2015-01-01)
    Article
    Open Access
    We introduce robots as a tools to enhance Ambient Assisted Living (AAL) services. Robots are a unique opportunity to create new systems to cooperate in reaching better living conditions. Robots offer the possibility of ...
  • DSP-based natural frame control schemes for three-phase unity-power-factor rectifiers 

    Guzmán Solà, Ramon; García de Vicuña Muñoz de la Nava, José Luis; Pena Alzola, Rafael (The institution of Engineering and Technology, 2016-05-01)
    Part of book or chapter of book
    Restricted access - publisher's policy
    Traditionally, digital signal processor (DSP) control algorithms for three-phase power converters are designed in rotating or stationary reference frames. These approaches require the use of rotation matrices and employ ...
  • Robust fault detection of singular LPV systems with multiple time-varying delays 

    Hassanabadi, Amir Hossein; Shafiee, Masoud; Puig Cayuela, Vicenç (2016-03-01)
    Article
    Open Access
    In this paper, the robust fault detection problem for LPV singular delayed systems in the presence of disturbances and actuator faults is considered. For both disturbance decoupling and actuator fault detection, an unknown ...
  • Modeling robot's world with minimal effort 

    Villamizar Vergel, Michael Alejandro; Garrell Zulueta, Anais; Sanfeliu Cortés, Alberto; Moreno-Noguer, Francesc (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Conference report
    Open Access
    We propose an efficient Human Robot Interaction approach to efficiently model the appearance of all relevant objects in robot’s environment. Given an input video stream recorded while the robot is navigating, the user just ...
