| 摘 要： | 根据半球谐振陀螺的动力学方程和闭环反馈理论,推导出离散激励器和信号检测器在壳体环向的角度配置;研究了在力平衡模式下半球谐振陀螺的信号闭环检测方法.当陀螺壳体绕中心轴旋转时,由于哥氏效应,谐振子振型相对壳体产生进动,通过控制双点激励力的幅值比,实现振型对壳体转动角度的跟踪,从而完成半球谐振陀螺在力平衡模式下的信号检测.

| Abstract: | According to the dynamical equation and the theory of closed loop feedback, the angle scheme of signal detector and discrete exciter in circumferential direction is deduced. This paper studies the signal closed-loop detecting method of hemispherical resonator gyro based on force rebalance. When the gyro shell rotates around its central axis, Coriolis Effect will cause procession of the vibration pattern relative to the shell. By controlling the amplitude ration of double points exciting forces, it is realized that the vibration pattern follows the rotating angle of the shell. Then signal detection is finished based on force rebalance. |
