  • On teaching model-based fault diagnosis in engineering curricula 

    Costa Castelló, Ramon; Puig Cayuela, Vicenç; Blesa Izquierdo, Joaquim (2016-02-01)
    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 ...
  • Real-Time Non-Intrusive Assessment of Viewing Distance During Computer Use

    Purpose: To develop and test the sensitivity of an ultrasound-based sensor to assess the viewing distance of visual display terminals operators in real-time conditions. Methods: A modified ultrasound sensor was attached ...
  • Fault tolerant control of a proton exchange membrane fuel cell using Takagi-Sugeno virtual actuators 

    Rotondo, Damiano; Nejjari Akhi-Elarab, Fatiha; Puig Cayuela, Vicenç (2016-09-01)
    Article
    Accés restringit per política de l'editorial
    In this paper, a fault tolerant control (FTC) strategy for proton exchange membrane (PEM) fuel cells based on the use of virtual actuators and the Takagi- Sugeno (TS) approach is proposed. The overall solution relies on ...
  • Stock management in hospital pharmacy using chance-constrained model predictive control 

    Jurado, Isabel; Maestre Torreblanca, José María; Velarde, Pablo; Ocampo-Martínez, Carlos; Fernandez, Isabel; Isla Tejera, Beatriz; del Prado, José Ramón (Elsevier, 2016-05-01)
    Article
    Accés restringit per política de l'editorial
    One of the most important problems in the pharmacy department of a hospital is stock management. The clinical needs of drugs must be satisfied with limited work labor while minimizing the use of economical resources. The ...
  • Stochastic model predictive control based on Gaussian processes applied to drinking water networks 

    Wang, Ye; Ocampo-Martínez, Carlos; Puig Cayuela, Vicenç (2016-05-16)
    Article
    Accés obert
    This study focuses on developing a stochastic model predictive control (MPC) strategy based on Gaussian processes (GPs) for propagating system disturbances in a receding horizon way. Using a probabilistic system representation, ...
  • 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 ...
  • Robust fault detection of singular LPV systems with multiple time-varying delays 

    Hassanabadi, Amir Hossein; Shafiee, Masoud; Puig Cayuela, Vicenç (2016-03-01)
    Article
    Accés obert
    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 ...
  • Formalism for a multiresolution time series database model 

    Llusa Serra, Aleix; Vila Marta, Sebastià; Escobet Canal, Teresa (2016-03)
    Article
    Accés restringit per política de l'editorial
    We formalise a specialised database management system model for time series using a multiresolution approach. These special purpose database systems store time series lossy compressed in a space-bounded storage. Time series ...
