Saturation effects detecting additive faults

2001 European Control Conference (ECC), 2001
This paper describes the effects of input saturation in model-based fault diagnosis. A linear model has been used for the residual generator, in order to show its lack of robustness. The experiments have been developed on a simple simulation case: a liquid tank.

Detecting and diagnosing saturation faults

UKACC International Conference on Control. Control '96, 1996
This paper presents a simple method for the detection and diagnosis of saturation faults in actuators for closed loop control systems. These faults are regarded as unexpected changes of the saturation level of the actuators. Assuming that there is a unknown nonlinear function which represents the relationship between the saturation and closed loop ...

A CT saturation detection algorithm

IEEE Transactions on Power Delivery, 2004
This paper proposes an algorithm for detecting current transformer (CT) saturation by analyzing a secondary current. The current has points of inflection where saturation begins and ends. Then, discontinuity in the first difference of the current arises at the next instants of points of inflection, where the second and third differences of the current ...

Harmonic saturated spectroscopy for improved atomic detection

Applied Optics, 1980
A novel method for improved cw laser-induced atomic fluorescence detection that we call harmonic saturated spectroscopy takes advantage of the nonlinear response of an optically saturated atomic system to reject background sources of interference. A reduction in background and an improved SNR are demonstrated for sodium detection in an air-acetylene ...

Harmonic saturated spectroscopy applied to molecular photoacoustic detection

Applied Optics, 1985
The feasibility of the application of harmonic saturated spectroscopy to molecular detection in the infrared regime was investigated. Experimental measurements using SF6 as a model gas were performed with a CO2 laser photoacoustic molecular vapor detector operating in the 9–11-μm portion of the infrared regime.

CT Saturation Detection and Compensation Algorithm

2020
This division presents a new Current Transformer (CT) saturation detection and compensation algorithm. The proposed algorithm depends on a saturation detection index (Dn) which is derived using derivatives of current signals and Newton’s backward difference formulas.

In vivo detection of hemoglobin oxygen saturation and carboxyhemoglobin saturation with multiwavelength photoacoustic microscopy

Optics Letters, 2012
A method for noninvasively detecting hemoglobin oxygen saturation (SO2) and carboxyhemoglobin saturation (SCO) in subcutaneous microvasculature with multiwavelength photoacoustic microscopy is presented. Blood samples mixed with different concentrations of carboxyhemoglobin were used to test the feasibility and accuracy of photoacoustic microscopy ...

Detection of Saturation and Artifact

2018
During the pulse signal acquisition, corruptions would be inevitably introduced such as high-frequency noise, baseline drift, saturation, and artifact. Some of the corrupted pulse signals can be recovered via preprocessing, but several types of corrupted pulse signals would be difficult to recover and should be removed from the pulse signal dataset ...

Detection of Paramagnetic Resonance by Saturation Effect

Review of Scientific Instruments, 1973
Bloch equations are solved in amplitude modulation of the rf field, and it is shown how the saturation can be put to use in obtaining a new kind of detection. A practical realization of a saturation effect spectrometer is given and some experimental results shown.

Detecting Saturation Attacks in Software-Defined Networks

2018 IEEE International Conference on Intelligence and Security Informatics (ISI), 2018
Software-Defined Networking (SDN) is a new net-working paradigm that has revolutionized network architectures. The separation of data and control planes improves the efficiency of packet delivery. However, there exist various security attacks against SDN systems.
