  • 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 ...
  • Robust H2 static output feedback to control an autmomotive throttle valve 

    Vargas, Alessandro; Acho Zuppa, Leonardo; Pujol Vázquez, Gisela; Oliveira, Ricardo C.L.F.; do Val, Joao B.R.; Peres, Pedro L.D. (2014)
    Conference lecture
    Open Access
    The paper presents a control strategy for an automotive electronic throttle body, a device largely used into vehicles to increase the efficiency of the combustion engines. The synthesis of the proposed controller is based ...
  • Nonlinear reset integrator control design: Application to the active suspension control of vehicles 

    Acho Zuppa, Leonardo (ACTA Press, 2014)
    Conference lecture
    Open Access
    We present an unexampled reset integrator control design based on the Clegg integrator system. Using an appropriate mathematical model of our Clegg integrator controller, stability proof of the closed-loop system applied ...
  • Comparison of the occupational hazards in the Spanish mining sector based on the type of workplace in the period 2003-2012 

    Sanmiquel Pera, Lluís; Freijo Álvarez, Modesto; Rossell Garriga, Josep Maria; Bascompta Massanés, Marc (2014)
    Conference lecture
    Restricted access - publisher's policy
    Methods and background: This review has done a comparison of the 3 types of workplace in the Spanish mining sector. The 3 workplaces considered are: mines, quarries and mineral processing plants. The 10 most frequent ...
  • Nuevo ciclo para el proyecto de investigación e innovación en metodologías del aprendizaje (RIMA) 

    Torra Bitlloch, Immaculada; Pozo Montero, Francesc; Salán Ballesteros, Maria Núria; Adam Salvatierra, Araceli (2013)
    Conference lecture
    Open Access
    El proyecto RIMA (Recerca i Innovació en Metodologies d’Aprenentatge / Investigación e innovación en metodologías de aprendizaje) es un proyecto institucional de la Universitat Politècnica de Catalunya – UPC BarcelonaTech, ...
