| 摘 要： | 分析了石英音叉陀螺连接电路中采样电阻的等效电容(电容特性)对测试的影响,求出了陀螺等效参数,找出了理想工作点.根据陀螺连接电路,针对考虑和不考虑采样电阻的等效电容两种情况进行建模,利用基于初等反射阵(Householder矩阵)变换的最小二乘法求出陀螺两组等效参数,通过仿真对比说明了采样电阻的等效电阻对测试结果有影响,测试中必须考虑.通过求得的参数进行仿真研究,说明了陀螺的真实串联谐振频点为陀螺的理想工作点.

| Abstract: | The influenceof the sampling resistance equal capacitance in the gyro's connection circuit on the test is analyzed.The gyro's equal parameters are gained,and the gyro's ideal resonance frequency is got.Based on the gyro' s connection circuit,the gyro's two models have been established with and without considering the sampling resistance's equal capacitance.Two group of the gyro's equal parameters are gained utilizing least square based on the Householder matrix transform.The conclusion that resistance's equ... |
