Investigation on Reciprocating Engine Pattern Recognition by Combining SVM and Hilbert Spectrum Entropy

Hongkun Li; Xiaojiang Ma; Fengtao Wang; Quanmin Ren Sixth International Conference on Intelligent Systems Design and Applications, 2006

Most of artificial intelligence methods used in pattern recognition for reciprocating engine is not very suitable for practical application because fault samples are very few. Support vector machine (SVM) is a new general machine-learning tool based on statistical learning method. It has good performance even when fault samples are few. In this paper, reciprocating engine pattern recognition based on SVM ...

Reduced interference distributions for the detection and classification of outside sound source acoustic emissions

J. C. Mossing; T. A. Tuthill 1996 IEEE International Conference on Acoustics, Speech, and Signal Processing Conference Proceedings, 1996

The problem of detecting and classifying outside sound sources (i.e. diesel engines, rotors, etc.) by their acoustic emissions is applicable to a number of industries. The key to successful detection and classification is selecting harmonically related narrowband peaks in the frequency domain. These harmonically related narrowband features an directly attributed to physical phenomena (i.e. engine firing rates and rotor RPM). ...

Engine fault diagnosis based on the weighted DS evidence theory

Zhuting Yao; Hongxia Pan 2014 IEEE 7th International Workshop on Computational Intelligence and Applications (IWCIA), 2014

Engine as a typical reciprocating power machinery, its complex structure determines its fault complexity and diversity, from the operating environment, system noise and sensor accuracy brings the uncertainties effect, results in accuracy rate lower of engine fault diagnosis, taking into account the limitations of traditional DS evidence theory, weighted DS evidence theory are studied. Finally, the engine as an example, ...
