    • Actuator-fault detection and isolation based on set-theoretic approaches 

      Xu, Feng; Puig Cayuela, Vicenç; Ocampo-Martínez, Carlos; Stoican, Florin; Olaru, Sorin (2014-06-01)
      Article
      Accés obert
      In this paper, an actuator-fault detection and isolation (FDI) approach is proposed. The FDI approach is based on a bank of interval observers, each of which is designed to match a healthy or faulty system mode. To ensure ...

    • Diagnosis and fault-tolerant control using set-based methods 

      Xu, Feng (Universitat Politècnica de Catalunya, 2014-11-27)
      Tesi
      Accés obert
      The fault-tolerant capability is an important performance specification for most of technical systems. The examples showing its importance are some catastrophes in civil aviation. According to some official investigations, ...

    • Estimation in uncertain switched systems using a bank of interval observers: local vs glocal approach 

      Rotondo, Damiano; Efimov, Denis; Cristofaro, Andrea; Johansen, Tor Arne (Elsevier, 2020)
      Text en actes de congrés
      Accés obert
      This paper discusses some issues related with the design of a bank of interval observers for uncertain switched systems, in which several sources of uncertainty are considered: parametric uncertainties, unknown disturbances, ...

    • Fault detection and isolation based on the combination of a bank of interval observers and invariant sets 

      Xu, Feng; Stoican, Florin; Puig Cayuela, Vicenç; Ocampo-Martínez, Carlos; Olaru, Sorin (2013)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      In this paper, a fault detection and isolation (FDI) approach using a bank of interval observers is developed. From the methodological point of view, a bank of interval observers is designed according to different dynamical ...

    • Fault diagnosis in wind turbines based on ANFIS and Takagi–Sugeno interval observers 

      Puig Cayuela, Vicenç; Pérez Pérez, Esvan de Jesús; Santos Ruiz, Ildeberto de los; López Estrada, Francisco Ronay; Valencia Palomo, Guillermo (2022-11)
      Article
      Accés restringit per política de l'editorial
      Wind turbine power generation is becoming one of the most critical renewable energy sources. As wind power grows, there is a need for better monitoring and diagnostic strategies to maximize energy production and increase ...

    • Fault tolerant control of uncertain dynamical systems using interval virtual actuators 

      Rotondo, Damiano; Cristofaro, Andrea; Johansen, Tor Arne (2018-01-25)
      Article
      Accés obert
      In this paper, a model reference fault tolerant control strategy based on a reconfiguration of the reference model, with the addition of a virtual actuator block, is presented for uncertain systems affected by disturbances ...

    • On robust interval observer design for uncertain systems subject to both time-invariant and time-varying uncertainties 

      Pourasgharlafmejani, Masoud; Puig Cayuela, Vicenç; Ocampo-Martínez, Carlos (2020-06-05)
      Article
      Accés obert
      This paper proposes the design of an interval observer-based approach for linear dynamic systems aected by both time-invariant and time-varying uncertainties. First, dierent interval observer schemes are compared and ...

    • Robust fault diagnosis of proton exchange membrane fuel cells using a Takagi-Sugeno interval observer approach 

      Rotondo, Damiano; Fernández Canti, Rosa M.; Tornil Sin, Sebastián; Blesa Izquierdo, Joaquim; Puig Cayuela, Vicenç (2016-01-07)
      Article
      Accés obert
      In this paper, the problem of robust fault diagnosis of proton exchange membrane (PEM) fuel cells is addressed by introducing the Takagi-Sugeno (TS) interval observers that consider uncertainty in a bounded context, adapting ...

    • Robust zonotopic observer design: Interval observer versus set-membership approaches 

      Pourasgharlafmejani, Masoud; Puig Cayuela, Vicenç; Ocampo-Martínez, Carlos (Institute of Electrical and Electronics Engineers (IEEE), 2019)
      Text en actes de congrés
      Accés obert
      The aim of this paper is to provide a robust observer design using a Linear Matrix Inequality (LMI) technique along with the analysis and comparison of the interval observer and set-membership approaches within the state ...
