粒子滤波在含噪齿轮箱故障盲源分离中的应用
Application of Particle Filter in Blind Source Separation of Gearbox Fault under Complex Noise Environment
摘要
Abstract
In gearbox fault diagnosis,the signals collected by sensors were suffered generally by the disturbance from various types of unknown noises.Under the complex noise environments,the blind source separation of the gearbox faults can not obtain perfect results of separation.In order to solve this problem,a new noisy blind source separation method of gearbox faults was proposed based on particle filter.A denoising process to the observation signals was implemented using Rao-blackwellised particle filter before the independent component analysis.The simulation and experimental results show that the proposed method is effective.关键词
