  • Advanced design of integrated vibration control systems for adjacent buildings under seismic excitations 

    Palacios Quiñonero, Francisco; Rubió Massegú, Josep; Rossell Garriga, Josep Maria; Karimi, Hamid Reza (2016)
    Conference report
    Open Access
    In vibration control of adjacent buildings under seismic excitations, a twofold objective has to be considered: (i) to mitigate the vibrational response of the individual structures and (ii) to provide a suitable protection ...
  • An educational example to the maximum power transfer objective in electric circuits using a PD-controlled DC- driver 

    Acho Zuppa, Leonardo (2016)
    Conference report
    Open Access
    The main objective of this paper is to present an academic example of a PD controller applied to teach position control design of a DC-motor to automatically adjust a potentiometer. This adjustment is focused on to solve ...
  • Super-twisting controllers for wind turbines 

    Tutivén Gálvez, Christian; Vidal Seguí, Yolanda; Acho Zuppa, Leonardo; Rodellar Benedé, José (2016)
    Conference report
    Open Access
    The main contribution of this paper is to propose new control techniques which not only provide fault tolerance capabilities to the WT system, but also improve the overall performance of the system in both fault free and ...
  • Variable structure strategy to avoid torque control saturation of a wind turbine in the presence of faults 

    Tutivén Gálvez, Christian; Vidal Seguí, Yolanda; Acho Zuppa, Leonardo; Rodellar Benedé, José (2016)
    Conference report
    Open Access
    Every physical actuator is subject to saturation. It has been well recognized that, when the actuator saturates, the performance of the closed-loop system (designed without considering actuator saturation) may seriously ...
  • CSI algorithm: ‘Canal Survey Estimation’ to estimate the flow rate extracted from irrigation canals 

    Soler Guitart, Joan; Bonet Gil, Enrique; Gómez Valentín, Manuel; Rodellar Benedé, José (Edicions de la Universitat de Lleida (UdL), 2015)
    Conference report

    The management of the water resources in a canal can be disturbed by the users, if the demand deliveries have been increased because a farmer obtained a greater flow than the scheduled delivery, the watermaster does not ...
  • Vibration control of hysteretic base-isolated structures: an LMI approach 

    Pozo Montero, Francesc; Pujol Vázquez, Gisela; Acho Zuppa, Leonardo (2016)
    Article
    Restricted access - publisher's policy
    Seismic isolation systems are essentially designed to preserve structural safety, prevent occupants injury and properties damage. An active saturated LMI-based control design is proposed to attenuate seismic disturbances ...
  • Tracking control for a Stewart platform prototype 

    Rossell Garriga, Josep Maria; Palacios Quiñonero, Francisco; Rubió Massegú, Josep; Vicente Rodrigo, Jesús (2015)
    Conference report

    A Stewart platform is a well-known mechanism which can be used for a wide variety of vibration control problems. In this paper, an LQR controller for a Stewart platform prototype is proposed which, combined with a proportional ...
  • Passive and hybrid mitigation of potential near-fault inner pounding of a self-braking seismic isolator 

    Abdel Kareem Moustafa, Mohamed Ismail; Rodellar Benedé, José; Pozo Montero, Francesc (2015-02-01)
    Article
    Open Access
    A seismic isolated structure is usually a long-period structural system, which may encounter a low-frequency resonance problem when subjected to a near-fault earthquake that usually has a long-period pulse-like waveform. ...
  • Seismic behavior of RNC-isolated bridges: a comparative study under near-fault, long-period, and pulse-like ground motions 

    Ismail, Mohammed; Rodellar Benedé, José; Casas Rius, Joan Ramon (2016-01)
    Article
    Open Access
    This paper introduces a recent seismic isolation system, named Roll-in-Cage (RNC) isolator, for efficient protection of bridges against destructive earthquakes. The RNC isolator is a rolling-based isolation system with ...
  • On the passivity of hysteretic systems with double hysteretic loops 

    Pozo Montero, Francesc; Zapateiro De La Hoz, Mauricio Fabian (2015-12-03)
    Article
    Open Access
    The Bouc–Wen hysteresis model is widely employed to mathematically represent the dynamical behavior of several physical devices, materials and systems such as magnetorheological dampers, lanthanide zirconium or aluminum ...
