Frequency Measuring Method Based on SVD and Improved ALE Arithmetic for Gas Coriolis Flowmeter
摘要
Abstract
Frequency calculation is the primary task of the gas coriolis flowmeter signal processing. According to the low signal noise ratio,frequency fluctuation of gas signal in the practical application,a new method based on the improved Adaptive Linear Enhance ( ALE ) frequency calculation is presented:In this method we first used the singular value decomposition( SVD) to denoising and reconstructing the original signal of gas signal,then applied the improved adaptive algorithm for signal reconstruction,and calculated the frequency. The simulation and experimental results show that,this method can obtain a faster convergence speed and higher frequency tracking accuracy.关键词
