  • Fault tolerant control for wind turbine pitch actuators 

    Rodellar Benedé, José; Acho Zuppa, Leonardo; Tutivén Gálvez, Christian; Vidal Seguí, Yolanda (2015)
    Conference report
    Open Access
    This paper develops a fault detection and isolation (FDI) and active fault tolerant control (FTC) of pitch actuators in wind turbines (WTs). This is accomplished combining a disturbance compensator with a controller, both ...
  • On the stability in probability of Markov jump systems with quadratic terms 

    Vargas, Alessandro N.; Pujol Vázquez, Gisela; Acho Zuppa, Leonardo; do Val, Joao B.R. (2015)
    Conference lecture
    Restricted access - publisher's policy
    The note presents conditions to assure the stability in probability for a class of continuoustime quadratic Markov jump systems. From the viewpoint of the state-space evolution, the system has two parts: (i) a linear term, ...
  • Principal component analysis and self-organizing maps for damage detection and classification under temperature variations 

    Anaya Vejar, Maribel; Tibaduiza Burgos, Diego Alexander; Torres-Arredondo, Miguel Ángel; Pozo Montero, Francesc (2015)
    Conference lecture
    Open Access
    The use of statistical techniques for data driven has proven very useful in multivariable analysis as a pattern recognition approach. Among their multiple advantages such as data reduction, multivariable analysis and the ...
  • Detection of structural changes through principal component analysis (PCA) and multivariate statistical inference 

    Pozo Montero, Francesc; Arruga Cantalapiedra, Ignacio; Mujica Delgado, Luis Eduardo; Podivilova, Elena (2015)
    Conference lecture
    Open Access
    This paper is focused on the development of a damage detection indicator that combines a data driven baseline model (reference pattern obtained from the healthy structure) based on principal component analysis (PCA) and ...
  • A fault detection method for pitch actuators faults in wind turbines 

    Tutivén Gálvez, Christian; Vidal Seguí, Yolanda; Acho Zuppa, Leonardo; Rodellar Benedé, José (2015)
    Conference report
    Open Access
    The paper presents a model-based fault detection method for pitch actuators faults using the normalized gradient method to estimate the parameters of the pitch actuator. One major difficulty is that the input signal to the ...
  • Semi-active control of flexible structures using acceleration information via peak-detector systems 

    Pujol Vázquez, Gisela; Acho Zuppa, Leonardo (Centre Internacional de Mètodes Numèrics en Enginyeria (CIMNE), 2014)
    Conference report
    Restricted access - publisher's policy
    This paper presents an implementation of a novel semi-active controller that uses only acceleration information, via a magnetorheorological damper, on a flexible structure. This controller was motivated by the scheme of a ...
  • Automatic damage classification based on wave cluster and principal component analysis 

    Garibnezhad, Fahit; Mujica Delgado, Luis Eduardo; Rodellar Benedé, José; Fritzen, Claus-Peter (2013)
    Conference lecture
    Open Access
    Principal Component Analysis (PCA) plays a significant role in SHM field. There are plenty of algorithms that use PCA either directly or indirectly to detect damages in structures. Although PCA shows a successful role ...
  • A secure communication system based on a modified chaotic chua oscillator 

    Zapateiro, Mauricio; Acho Zuppa, Leonardo; Vidal Seguí, Yolanda (2014)
    Conference lecture
    Open Access
    In this paper we propose a new scheme for secure communications us- ing a modified Chua oscillator. A modification of the oscillator is proposed in order to facilitate the decryption. The communication system requires two ...
  • Static output-feedback controller design for structural vibration control: a two-step LMI approach 

    Palacios Quiñonero, Francisco; Rubió Massegú, Josep; Rossell Garriga, Josep Maria; Karimi, Hamid Reza (2014)
    Conference report
    Restricted access - publisher's policy
    This paper presents a novel controller design strategy, which allows computing static output-feedback controllers by solving two successive linear matrix inequality (LMI) optimization problems. This strategy is conceptually ...
  • Discrete-time static output-feedback H-infinity controller design for vehicle suspensions 

    Palacios Quiñonero, Francisco; Rubió Massegú, Josep; Rossell Garriga, Josep Maria; Karimi, Hamid Reza (2014)
    Conference report
    Open Access
    This paper provides a direct and practical presentation of a novel methodology for static output feedback controller design. The proposed design strategy has been successfully applied in the fields of control systems for ...
