A comparative study of energy graph-based fault detection and isolation techniques applied to a lignite plant [PDF]
Heliyon, 2023 Energy and exergy interactions in industrial systems hold meaning across physical domains. This paper builds on the notion that capturing the energy and exergy interactions of a system, while retaining physical structural context, enables fault detection

Fault Detection and Isolation of the Multi-Sensor Inertial System [PDF]
Micromachines, 2021 In order to solve the problem that the generalized likelihood test method cannot isolate the single fault of the four-gyro system and the double faults of the six-gyro system, a fault detection and isolation method combining the generalized likelihood ...

Real-Time Neural Classifiers for Sensor and Actuator Faults in Three-Phase Induction Motors
Machines, 2022 The main steps involved in a fault-tolerant control (FTC) scheme are the detection of failures, isolation and reconfiguration of control. Fault detection and isolation (FDI) is a topic of interest due to its importance for the controller, since it ...

Delays in fault detection and isolation [PDF]
Proceedings of the 2001 American Control Conference. (Cat. No.01CH37148), 2001 Studies an aspect of detection and isolation delays which has been ignored in many papers in this area. Surprising since it is highly relevant from a practical point of view. In continuous-time systems this is not a serious matter since we can always guarantee an arbitrary small delay and nearly all designs in the literature yield this arbitrary small ...
