Actuator-fault detection and isolation based on set-theoretic approaches
(2014-06-01)
Article.
Accés obert
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 ...
Robust MPC for actuator-fault tolerance using set-based passive fault detection and active fault isolation

In this paper, an actuator fault-tolerant control (FTC) scheme is proposed, which is based on tube-based model predictive control (MPC) and set-theoretic fault detection and isolation (FDI). As a robust MPC technique, ...

In this paper, the problem of fault diagnosis of a wind farm is addressed using interval parity equations. Fault detection is based on the use of parity equations and unknown but bounded description of
the noise and ...

Article.
Accés restringit per política de l'editorial
In this paper, an integrated data validation/reconstruction and fault diagnosis approach is proposed for critical infrastructure systems. The proposed methodology is implemented in a two-stage approach. In the first stage, ...

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 ...
