    This paper describes the experimental identifi- cation of the parameters of the Twin Rotor MIMO System (TRMS) non-linear model using data collected from the real lab set-up. From this non-linear model, ...
  • Fault estimation and virtual sensor FTC approach for LPV systems 

    Montes de Oca, Saúl; Rotondo, Damiano; Nejjari Akhi-Elarab, Fatiha; Puig Cayuela, Vicenç (Institute of Electrical and Electronics Engineers (IEEE), 2011)
    Conference report

    In this paper, a Fault Tolerant Control (FTC) strategy using a virtual sensor for Linear Parameter Varying (LPV) systems is proposed. The main idea of this FTC method is to reconfigure the control loop such that the nominal ...
  • Modeling robot's world with minimal effort 

    Villamizar Vergel, Michael Alejandro; Garrell Zulueta, Anais; Sanfeliu Cortés, Alberto; Moreno-Noguer, Francesc (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Conference report
    Open Access
    We propose an efficient Human Robot Interaction approach to efficiently model the appearance of all relevant objects in robot’s environment. Given an input video stream recorded while the robot is navigating, the user just ...
  • Unfalsified adaptive control for manipulators with parameter uncertainties 

    Arango Castro, Jaime Enrique; Ocampo-Martínez, Carlos; Bianchi, Fernando Daniel; Osorio Londoño, Gustavo Adolfo (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Conference report
    Open Access
    This work evaluates by simulation the performance of the Unfalsified Adaptive Control (UAC) for Multiple Degree of Freedom (MDoF) serial manipulators. The UAC is a data-driven technique that addresses stability issues of ...
  • Temperature regulation of a pilot-scale batch reaction system via explicit model predictive control 

    Sánchez Cossio, Javier; Ortega Álvarez, Juan David; Ocampo-Martínez, Carlos (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Conference report
    Open Access
    In this paper, the temperature of a pilot-scale batch reaction system is modeled towards the design of a controller based on the explicit model predictive control (EMPC) strategy. Some mathematical models are developed ...
  • Variation tolerant self-adaptive clock generation architecture based on a ring oscillator 

    Pérez Puigdemont, Jordi; Calomarde Palomino, Antonio; Moll Echeto, Francisco de Borja (Institute of Electrical and Electronics Engineers (IEEE), 2012)
    Conference lecture
    Open Access
    In this work we propose a self-adaptive clock based on a ring oscillator as the solution for the increasing uncertainty in the critical path delay. This increase in uncertainty forces to add more safety margins to the ...
  • Assessing pediatrics patients’ psychological states from biomedical signals in a cloud of social robots 

    Díaz Boladeras, Marta; Angulo Bahón, Cecilio; Domènech Argemí, Miquel; Albo Canals, Jordi; Serrallonga, Núria; Raya Giner, Cristóbal; Barco, Alex (Springer, 2016)
    Conference report
