    • Actuator-fault detection and isolation based on interval observers and invariant sets 

      Xu, Feng; Puig Cayuela, Vicenç; Ocampo-Martínez, Carlos; Stoican, Florin; Olaru, Sorin (Institute of Electrical and Electronics Engineers (IEEE), 2013)
      Conference report

      This paper proposes an interval observer-based actuator fault detection and isolation (FDI) approach. An interval observer matching the healthy system mode is designed to monitor the system. When the system is in different ...
    • 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
      Open Access
      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 ...

      Conference report
      Restricted access - publisher's policy
      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 handling in large water networks with online dictionary learning 

      Irofti, Paul; Stoican, Florin; Puig Cayuela, Vicenç (2020-10-01)
      Article
      Restricted access - publisher's policy
      Fault detection and isolation in water distribution networks is an active topic due to the nonlinearities of flow propagation and recent increases in data availability due to sensor deployment. Here, we propose an efficient ...

    • On the relationship between interval observers and invariant sets in fault detection 

      Xu, Feng; Stoican, Florin; Puig Cayuela, Vicenç; Ocampo-Martínez, Carlos; Olaru, Sorin (2013)
      Conference report
      Restricted access - publisher's policy
      In this paper, the relationship between two settheoretic fault detection (FD) approaches, the interval observerbased and the invariant set-based approaches, is investigated. In FD, interval observers monitor the system ...
    • Sensor-fault detection and Isolation using Interval Observers 

      Xu, Feng; Puig Cayuela, Vicenç; Ocampo-Martínez, Carlos; Stoican, Florin; Olaru, Sorin (2013)
      Conference report
      Restricted access - publisher's policy
      This paper proposes an interval observer-based sensor fault detection and isolation (FDI) approach for the closed-loop systems. In this proposed approach, residuals are defined in such a way that their components are ...
