    The success of any diagnosis strategy critically depends on the sensors measuring process variables. This paper presents a strategy based on diagnosability maximization for optimally locating sensors in distribution networks. ...
  • Quasi-LPV modelling and non-linear identification of a twin rotor system

    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 ...
  • 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 ...
  • An application of the Shapley value to perform system partitioning 

    Muros Ponce, Francisco; Maestre Torreblanca, José María; Algaba Durán, Encarnación; Ocampo-Martínez, Carlos; Fernández Camacho, Eduardo (2015)
    Conference report
    Open Access
    We introduce a new method to perform the partitioning of non-centralized dynamical linear systems based on the relevance of the possible interconnections among the smallest components of the system. In particular, we analyze ...
  • Icing detection in unmanned aerial vehicles with longitudinal motion using an LPV unknown input observer 

    Rotondo, Damiano; Cristofaros, A; Johansen, T; Nejjari Akhi-Elarab, Fatiha; Puig Cayuela, Vicenç (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Conference report
    Open Access
    This paper proposes a linear parameter varying (LPV) unknown input observer for the diagnosis of actuator faults and icing in unmanned aerial vehicles (UAVs). The accretion of ice layers on wings and control surfaces ...
  • Shifting linear quadratic control of constrained continuous-time descriptor LPV systems 

    Rotondo, Damiano; Nejjari Akhi-Elarab, Fatiha; Puig Cayuela, Vicenç (2015)
    Conference report
    Open Access
    Recently, the concept of shifting linear quadratic control (SLQC), where some varying parameters are introduced and used to schedule the weighting matrices of a quadratic cost function, has been introduced. This paper ...
  • On the anode pressure and humidity regulation in PEM fuel cells: a nonlinear predictive control approach 

    Rosanas Boeta, Noe; Ocampo-Martínez, Carlos; Kunusch, Cristian (2015)
    Conference report
    Open Access
    In this paper, a nonlinear model predictive control (NMPC) strategy is proposed to regulate the humidity in a Proton Exchange Membrane Fuel Cell (PEMFC) anode. The proposed control strategy uses two controllers in cascade ...
