压电射流角速度传感器的消噪研究

Filtering for Piezoelectric Fluidic Angular Velocity Sensor

本文分析了压电射流角速度传感器的噪声特点，提出了利用自适应数字滤波抑制其噪声，归纳了自适应算法中的快速模式滤波（FTF）最小二乘法的算法步骤，并且使用8098单片微机实现对该传感器的实时FTF滤波，给出了滤波效果实例。

This paper analysis the noise characteristics of the piezoelectric fluidic angular velocity sensors, uses the adaptive filtering to eliminate the noise and induces the FTF steps of the adaptive algorithm. The real-time FTF filtering of sensors is reallzed by means of 8098 sin-gle chip computer. The results of filtering are provided.
