  • 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 ...

    Article
    Accés obert
    Civil and military structures are susceptible and vulnerable to damage due to the environmental and operational conditions. Therefore, the implementation of technology to provide robust solutions in damage identification ...
  • 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 ...
