With the continuous improvement of ship building technology in various countries, the ship-
radiated noise signal (SRNS) in the ocean is becoming weaker and weaker, which makes …

Fault detection, with the characteristics of strong uncertainty and randomness, has always
been one of the research hotspots in the field of aerospace. Considering that devices will …

Drift detection has been a difficult problem in the field of sensor fault diagnosis. In this article,
a sensor drift detection method using discrete wavelet transform (DWT) and a grey model …

The Fourier transform is widely accepted as the time-to-frequency conversion procedure,
although it has some limitations. Currently, measurements in the time domain are usually …

利用溶剂热法制备了Er 3+ 掺杂的Cs2Sn0. 9Te0. 1Cl6 钙钛矿晶体, 利用SEM, XRD
等手段对材料进行了形貌表征, 并通过荧光光谱仪对材料的光学性能进行了表征 …

In this paper, a novel fault detection observer structure for aero-engine temperature sensor
faults is proposed. The observer structure overcomes the difficulty that the measured input …

For switchgear conformity inspection, a real-time wavelet transform inspection algorithm
based on the robot's qualification inspection scheme is proposed. The torque signal after …

This study reports on the development and implementation of the fuzzy incremental
controller on a small‐scale linear fresnel reflector solar plant. The control problem is …

The methanol three-column distillation process is often affected by noise and random
interference, which causes the normal data to be misreported as fault data when monitoring …

Vibration will lead to power grid disconnection, equipment rupture and other problems, so
the working status of the vibration sensor hanging the grid is closely related to the normal …
