| 摘 要： | 根据格型自适应的结构原理,运用了一种频率响应非对称的修正自适应格型陷波器(improved adaptive lattice notchfilter,I-ALNF)在科氏流量计上的应用,并把零极点参数全部引入自适应算法中,使得算法与陷波器完全匹配,且使陷波器具有更好的特性。仿真结果表明,修正格型自适应陷波器比格型自适应陷波器的频率跟踪精度更高,稳定性更好。

| Abstract: | According to the lattice adaptive structure principle, using a frequency response asymmetry correction adaptive lattice notch filter ( improved adaptive lattice notch filter, I-ALNF ) in the application of Coriolis mass flowmeter, and the zero pole parameters of all of the adaptive algorithm, so the algorithm and the notch filter match exactly, and the notch filter has better characteristics. The simulation results show that, modified lattice adaptive notch filter in adaptive notch filter frequency tracking accuracy is high, the stability is better. |
