Bearing Fault Diagnosis via ADALINE and Wavelet Packet Shannon Entropy
Ji Liu · Small & Special Electrical Machines · 2013
Based on many deficiencies that exist in bearing fault of synchronous generator diagnosis,the signals are easily influenced by the variation of the noise and the signal after fault is nonlinear and chaos.The method via ADAONE and wavelet packet Shannon entropy were introduced.The method of ADLINE was used to wipe out the noise.The different fault mode signals of Shannon entropy were calculated after wavelet packet analysis,and the Shannon entropy was used to distinguish the different bearing fault mode.Experiment results shows this method is useful,efficient,and easy to be used in engineering.
