  • Wind turbine fault detection through principal component analysis and statistical hypothesis testing 

    Pozo Montero, Francesc; Vidal Seguí, Yolanda (2016-10-31)
    Article
    Accés obert
    This work addresses the problem of online fault detection of an advanced wind turbine benchmark under actuators (pitch and torque) and sensors (pitch angle measurement) faults of different type. The fault detection scheme ...
  • A chaotic secure communication system design based on iterative learning control theory 

    Acho Zuppa, Leonardo (Multidisciplinary Digital Publishing Institute, 2016-10-01)
    Article
    Accés obert
    This paper presents an application of Iterative Learning Control (ILC) theory to secure communication system design by using chaotic signals, where the logistic-map is employed as a source of chaos. Meanwhile, the ILC ...
  • On the set of periods of the 2-periodic Lyness' equation 

    Bastien, Guy; Mañosa Fernández, Víctor; Rogalski, Marc (2012)
    Comunicació de congrés
    Accés restringit per política de l'editorial
    We study the periodic solutions of the non-autonomous periodic Lyness’ recurrence un+2=(an+un+1)/un, where {an}n is a cycle with positive values a,b and with positive initial conditions. Among other methodological issues ...
  • Novel results on decentralized H-infinity controller design for structural vibration control of large buildings 

    Palacios Quiñonero, Francisco; Rubió Massegú, Josep; Rossell Garriga, Josep Maria; Karimi, Hamid Reza (CRC Press, 2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    In this paper, we present a novel control design methodology for structural vibration control of large buildings. The main idea consists in decomposing the overall building system into decoupled single-story subsystems and ...
  • New offset-free method for model predictive control of open channels 

    Horváth, Klaudia; Galvis, Eduard; Gómez Valentín, Manuel; Rodellar Benedé, José (2015-08)
    Article
    Accés restringit per política de l'editorial
    Irrigation or drainage canals can be controlled by model predictive control (MPC). Applying MPC with an internal model in the presence of unknown disturbances in some cases can lead to steady state offset. Therefore an ...
  • Stochastic stability for a model representing the intake manifold pressure of an automotive engine 

    Vargas do Nascimiento, Alessandro; Acho Zuppa, Leonardo; Bonifacio, Edison; Arens, Walter; B. R. do Va, Joao (2016-09-23)
    Article
    Accés obert
    The paper presents conditions to assure stochastic stability for a nonlinear model. The proposed model is used to represent the input-output dynamics of the angle of aperture of the throttle valve (input) and the manifold ...
  • Order regularity for Birkhoff interpolation with lacunary polynomials 

    Palacios Quiñonero, Francisco; Rubio Díaz, Pedro; Díaz Barrero, José Luis; Rossell Garriga, Josep Maria (2011-06-01)
    Article
    Accés obert
    In this short paper we present sufficient conditions for the order regularity problem in Birkhoff interpolation with lacunary polynomials. These conditions are a generalization of the Atkinson-Sharma theorem.
  • Computational effectiveness of LMI design strategies for vibration control of large structures 

    Palacios Quiñonero, Francisco; Rubió Massegú, Josep; Rossell Garriga, Josep Maria; Karimi, Hamid Reza (2016)
    Text en actes de congrés
    Accés obert
    Distributed control systems for vibration control of large structures involve a large number of actuation devices and sensors that work coordinately to produce the desired control actions. Design strategies based on linear ...
  • A new method for the identification of the parameters of the Dahl model 

    García Baños, Isabel; Ikhouane, Fayçal (2016)
    Text en actes de congrés
    Accés obert
  • Acceleration-based fault-tolerant control design of offshore fixed wind turbines 

    Tutivén Gálvez, Christian; Vidal Seguí, Yolanda; Rodellar Benedé, José; Acho Zuppa, Leonardo (2016)
    Article
    Accés obert
    Wind turbines (WTs) are basically controlled by varying the generator load torque (with the so-called torque control) and the blade pitch angles (with the so-called pitch control) based on measurement of the generator shaft ...
