  • Sensor fault detection in a damage detection approach based on piezodiagnostics 

    Ruiz Ordóñez, Magda; Camacho-Navarro, Jhonatan; Villamizar Mejía, Rodolfo; Mujica Delgado, Luis Eduardo (2016)
    Text en actes de congrés
    Accés obert
    Online monitoring systems demand an adequate operation of sensor system used to acquire structural state measurements. If a damaged sensor record is incorporated in the diagnosis algorithm, it could be generate uncertainties ...
  • Sensor selection based on principal component analysis for fault detection in wind turbines 

    Pozo Montero, Francesc; Vidal Seguí, Yolanda (2016)
    Text en actes de congrés
    Accés obert
    Growing interest for improving the reliability of safety-critical structures, such as wind turbines, has led to the advancement of structural health monitoring (SHM). Existing techniques for fault detection can be broadly ...
  • Fault tolerant control design of floating offshore wind turbines 

    Rodellar Benedé, José; Tutivén Gálvez, Christian; Acho Zuppa, Leonardo; Vidal Seguí, Yolanda (2016)
    Text en actes de congrés
    Accés obert
    This work is concerned with active vibration mitigation in wind turbines (WT) but not through the use of specifically tailored devices. Instead, a general control scheme is designed for torque and pitch controllers based ...
  • Multidimensional big data processing for damage detection in real pipelines using a smart pig tool 

    Ruiz Ordóñez, Magda; Mujica Delgado, Luis Eduardo; Alférez Baquero, Edwin Santiago; Quintero, Mario; Villamizar Mejía, Rodolfo (2016)

    Accés obert
    The history of the hydrocarbons business in Colombia dates back to the early twentieth century where mining and energy sector has been one of the principal pillars for the its development. Thus, the pipelines currently in ...
  • Embedded piezodiagnostics for online structural damage detection based on PCA algorithm 

    Camacho-Navarro, Jhonatan; Ruiz Ordóñez, Magda; Villamizar Mejía, Rodolfo; Mujica Delgado, Luis Eduardo; Ariza, Fabian (2016)
    Text en actes de congrés
    Accés obert
    This work discusses a methodology used to implement a data-driven strategy for Structural Health Monitoring. First, the instrumentation of the equipment is detailed by describing the main components to be installed in the ...
  • Parameter identification of large-scale magnetorheological dampers in a benchmark building 

    Bahar, Arash; Pozo Montero, Francesc; Acho Zuppa, Leonardo; Rodellar Benedé, José; Barbat Barbat, Horia Alejandro (2009)
    Text en actes de congrés
    Accés obert
    Magnetorheological (MR) dampers are devices that can be use d for vibration re- duction in structures. However, to use these devices in an ef fective way, a precise modeling is required. In this sense, in this paper we ...
  • A continuous-time delay chaotic system obtained from a chaotic logistic map 

    Acho Zuppa, Leonardo (ACTA Press, 2017)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    This paper presents a procedure to transform a chaotic logistic map into a continuous-time delay chaotic system by using sampled-data representation of continuous-time models. Because of this, the chaotic behavior of the ...
  • 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 ...
  • 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 ...
