Fault diagnosis with dynamic observers [PDF]

open access: yes2008 9th International Workshop on Discrete Event Systems, 2008
In this paper, we review some recent results about the use of dynamic observers for fault diagnosis of discrete event systems. Fault diagnosis consists in synthesizing a diagnoser that observes a given plant and identifies faults in the plant as soon as possible after their occurrence.

Dynamic Modelling and Continuous Trajectory Tracking Control of Space Robots Based on Lie Group SE(3)

open access: yesInternational Journal of Aerospace Engineering, 2023
For space robots, it is difficult to track continuous time-varying manifolds on SE(3) by using traditional closed-loop control strategies, which are designed to track the position and the attitude separately.

An Effective Gear Fault Diagnosis Method Based on Singular Value Decomposition and Frequency Slice Wavelet Transform

open access: yesInternational Journal of Rotating Machinery, 2016
The ability of the frequency slice wavelet transform (FSWT) to distinguish the fault feature is weak under the condition of strong background noise; in order to solve this problem, a fault feature extraction method combining the singular value ...
