A Self-adaptive Fault Monitoring Method Based on EMD

Abstract

The effect of traditional fault monitoring methods was usually affected by the variations of equipment’s working condition. In view of this situation, a self-adaptive fault monitoring method by using empirical mode decomposition (EMD) and the energy comparison of different order intrinsic mode functions (IMF) was presented. The method can avoid the negative impact of equipment state changing and human intervention, has strong adaptability, and is proved by simulation.
