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

    Freier Zugriff

    Trabajo presentado a la 52nd CDC celebrada en Florencia del 10 al 13 de diciembre de 2013. ; 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 modes, state or output interval vectors predicted by the interval observer manifest different dynamical behaviors. To guarantee reliable FDI, a collection of invariant set-based FDI conditions are established. Under these conditions, actuator faults can be accurately detected and isolated during the transition between different modes. At the end, the effectiveness of this proposed approach is presented by using a numerical example. ; The work of F. Xu, V. Puig and C.
