Fault Detection, Diagnosis and Identification
1998In this work we distinguish between two kind of faults: slowly changing and abrupt changing faults. The first often originate from wearing and the latter from a abrupt errors within the process control system. In practice, a supervision system has to deal simultaneously with both types of faults, but here we make a distinction because different methods

Detection and Identification of Faults in Clock Ensembles
ION GNSS+, The International Technical Meeting of the Satellite Division of The Institute of Navigation, 2019The quality of the positioning and time dissemination services provided by Global Navigation Satellite Systems is tightly coupled with the provision of a stable system time scale. The robustness of time generation is important to ensure the continuity of service without performance degradation.

Identification of immune models for fault detection
Proceedings of the Institution of Mechanical Engineers, Part I: Journal of Systems and Control Engineering, 2004Abstract In this paper, a novel approach to model-based fault detection for non-linear systems is presented. An immune model of the system is used for the generation of residual. The orthogonal least-squares method is implemented to select the significant receptor vectors of the immune model.

Dynamic Structural Fault Detection and Identification
AIAA Guidance, Navigation, and Control Conference, 2009Aircraft structures are designed to guarantee safety of flight in some required operational envelope. When the aircraft becomes structurally impaired, safety of flight may not be guaranteed within that previously safe operational envelope. In this case the safe operational envelope must be redefined in-flight and a means to prevent excursion from this ...

An intelligent approach to fault detection and identification
Proceedings of 1995 American Control Conference - ACC'95, 2005A new approach is proposed for improving the performance of an intelligent fault detection and identification scheme for dynamic systems. The methodology uses short time Fourier transform to analyze the frequency contents of the input signal in real time through a moving window.
