    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 

    Pérez Magrané, Ramon; Puig Cayuela, Vicenç; Pascual Pañach, Josep; Quevedo Casín, Joseba Jokin; Landeros, E.; Peralta, Antoni (2011-07)
    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 ...
  • Robust fault diagnosis of proton exchange membrane fuel cells using a Takagi-Sugeno interval observer approach 

    Rotondo, Damiano; Fernández Canti, Rosa M.; Tornil Sin, Sebastián; Blesa Izquierdo, Joaquim; Puig Cayuela, Vicenç (2016-01-07)
    Article
    Accés restringit per política de l'editorial
    In this paper, the problem of robust fault diagnosis of proton exchange membrane (PEM) fuel cells is addressed by introducing the Takagi-Sugeno (TS) interval observers that consider uncertainty in a bounded context, adapting ...
  • A methodology and a software tool for sensor data validation/reconstruction : application to the Catalonia regional water retwork 

    Cugueró Escofet, Miquel Àngel; García Valverde, Diego; Quevedo Casín, Joseba Jokin; Puig Cayuela, Vicenç; Espin, Santiago; Roquet, Jaume (2016-04-01)
    Article
    Accés restringit per política de l'editorial
    In this paper, a sensor data validation/reconstruction methodology applicable to water networks and its implementation by means of a software tool are presented. The aim is to guarantee that the sensor data are reliable ...
  • Non-linear set-membership identification approach based on the Bayesian framework 

    Fernández Canti, Rosa M.; Tornil Sin, Sebastián; Blesa Izquierdo, Joaquim; Puig Cayuela, Vicenç (2015-06-06)
    Article
    Accés obert
    This study deals with the problem of set-membership identification of non-linear-in-the-parameters models. To solve this problem, this study illustrates how the Bayesian approach can be used to determine the feasible ...
  • Fault detection and isolation for a wind turbine benchmark using a mixed Bayesian/set-membership approach 

    Fernández Canti, Rosa M.; Blesa Izquierdo, Joaquim; Tornil Sin, Sebastián; Puig Cayuela, Vicenç (2015-10-30)
    Article
    Accés obert
    This paper addresses the problem of fault detection and isolation of wind turbines using a mixed Bayesian/Set-membership approach. Modeling errors are assumed to be unknown but bounded, following the set-membership approach. ...
