An Adaptive Notch Filter Algorithm on Frequency Calculation for Coriolis Mass Flowmeter
摘要
Abstract
This paper presents a new method of frequency calculation to improve Coriolis Mass Flowmeter signal frequency tracking convergence speed and accuracy. Firstly,based on Burg algorithm,lattice type IIR adaptive notch filter is adopted for signal filtering and tracks signal frequency in short time,then based on simplifying gradient algorithm lattice adaptive trap filter begins to work in parallel after the signal is converged,which continue working to the end. At the same time,based on Burg algorithm,lattice type IIR adaptive notch filter stops its work after convergence. Through experimental and simulation results the conclusions show that signals converge faster and tracking accuracy is higher.关键词
