摘要
提出了一种采用独立分量分析进行工程信号中工频干扰消除的新方法,可将混入振动信号中的工频干扰信号有效分离.对独立分量分析的基本原理进行简要介绍之后,通过仿真和实际测试对本方法的有效性进行了验证.
In this paper, a new independent component analysis approach to remove power frequency disturbance （ICA） is proposed, which can remove the power mixed vibration signals effectively. A brief introduction about the theory of ICA is from vibration signals based on frequency disturbance from the also presented. The validity of the proposed approach is verified by a simulation and test resuhs.
