为了减小谐振子偏心对力反馈模式下半球谐振陀螺输出的影响, 设计了3种振幅检测的方案。基于半球谐振子径向运动方程, 解算出了陀螺输出的表达式;推导出谐振子偏心情况下, 3种振幅检测方案测得的振幅;根据这些振幅, 得出了相应检测方案下的陀螺输出;通过仿真计算了每种方案的输出相对误差。从结果看出, 第3种检测方案极大地减小了谐振子偏心对半球陀螺输出的影响。

Abstract

To decrease the influence of resonator eccentricity to output of Hemispherical Resonator Gyroscope (HRG) in force feedback model, three schemes were designed to measure the resonator amplitude. Firstly, based on the dynamic motion equation of resonator in radial direction, the expression of gyros output was established. Then, the amplitude measured by different schemes was inferred in the condition of resonator eccentricity. Based on the amplitude, gyros output corresponding to each measurement scheme was obtained. At last, the output relative error of each scheme was calculated out by simulation. The simulation result showed that the third scheme has the best performance for decreasing the influence of resonator eccentricity to gyros output.
