压电陀螺信号处理与滤波技术研究

针对压电陀螺在工程上实际应用的需求,对其输出做了测试和建模,设计并实现了α-β滤波、卡尔曼滤波和小波滤波3种不同方法对该信号的噪声滤除,分别给出了滤波后陀螺输出信号图和标准差的对比.通过对试验数据的分析,肯定了3种方法在压电陀螺输出信号滤波处理中的有效性,并分析了各自的优缺点.

Study on Signal Processing and Filtering for Piezoelectric Gyroscope

According to the requirements of the engineering application, the output of the piezoelectric gyroscope is tested and modelled. The noise of signal is filtered out by three methods of the α-β filtering, kalman filtering and wavelet filtering and the comparison between the output signal graph of the gyroscope and the standard difference after filtering is made. Through the analysis of the experimental data, it shows that these three methods can greatly improve the precision of the piezoelectric gyroscope.
