1.
Analysis of differential pressure signal based on wavelet transform and higher-order statistics;
基于高阶统计量和小波变换的差压信号分析
2.
EMD is applied to the differential pressure signal of two-phase flow to obtain frequency components with different scales, and the normalized energy of the component is extracted as the feature of flow pattern identification.
应用EMD将差压信号分解成不同频率尺度上的单组分之和,并提取组分的归一化能量作为流型辨识特征量。
3.
Because the differential pressure signal of oil-gas two-phase flow was a typical non-stationary and multi-component signal,EMD was first applied to break up it into Intrinsic Mode Functions(IMFs) which can be divided into three frequency bands such as high-band(30~50 Hz),mid-band(5~30Hz) and low-band(0~5 Hz).
油气两相流差压信号是一典型的非平稳多组分信号,经验模态分解首先将差压信号分解成9阶本征模函数,按照频率范围可以划分为3个子带:高频带(30~50 Hz),中频带(5~30 Hz)和低频带(0~5 Hz)。
