    This paper proposes an observer for the joint state and fault estimation devoted to discrete-time linear parameter varying (LPV) systems subject to actuator faults. The major contribution of this work is that the observer ...
  • Model- vs. data-based approaches applied to fault diagnosis in potable water supply networks 

    Cugueró, Miquel Àngel; Quevedo Casín, Joseba Jokin; Alippi, Cesare; Roveri, Manuel; Puig Cayuela, Vicenç; García Valverde, Diego; Trovò, F (2016-05-10)
    Article
    Accés obert
    In this paper, the problem of fault diagnosis in drinking water transport networks (DWTNs) is addressed. Two different fault diagnosis approaches are proposed to deal with this problem. The first one is based on a ...
  • On teaching model-based fault diagnosis in engineering curricula

    Article
    Accés obert
    This article presents an example of how a fault-diagnosis course has been included in an engineering curricula in a motivating way, in particular, in the automatic control and robotic master's degree program at UPC. This ...
  • Robust unknown input observer for state and fault estimation in discrete-time Takagi-Sugeno systems 

    Rotondo, Damiano; Witczak, Marcin; Puig Cayuela, Vicenç; Nejjari Akhi-Elarab, Fatiha; Pazera, Marcin (2016-01-01)
    Article
    Accés obert
    In this paper, a robust unknown input observer (UIO) for the joint state and fault estimation in discrete-time Takagi-Sugeno (TS) systems is presented. The proposed robust UIO, by applying the H-infinity framework, leads ...
  • Methodology for leakage isolation using pressure sensitivity analysis in water distribution networks

    Article
    Accés restringit per política de l'editorial
    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
    Accés obert
    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 ...
  • Leak detection and localization through demand components calibration 

    Sanz Estapé, Gerard; Pérez Magrané, Ramon; Zoran, Kapelan; Savic, Dragan (2016-02-01)
    Article
    Accés obert
    Success in the application of any model-based methodology (e.g., design, control, supervision) highly depends on the availability of a well-calibrated model. The calibration of water distribution networks needs to be ...
  • Set-membership identification and fault detection using a Bayesian framework 

    Fernández Canti, Rosa M.; Blesa Izquierdo, Joaquim; Puig Cayuela, Vicenç; Tornil Sin, Sebastián (2016-05-18)
    Article
    Accés obert
    This paper deals with the problem of set-membership identification and fault detection using a Bayesian framework. The paper presents how the set-membership model estimation problem can be reformulated from the Bayesian ...
