摘要
Abstract
A signal processing method combining SVD and UKF for Coriolis flow meters is proposed to address the characteristics of slow signal variation and high measurement accuracy requirements under single-phase flow conditions.Firstly,the SVD algorithm is used to reduce the interference noise in the signal.Then,the state vector,state transition equation,and observation equation of the signal to be measured are established.The UKF algorithm is used to track the parameters of the two output signals of the measurement tube.Finally,the updated state estimation values are used to calculate the phase difference and signal frequency.The overall process and implementa-tion steps of the method are provided,and the feasibility of the entire algorithm is demonstrated through simulation and practical testing.The proposed method has certain application value.关键词
