新型高精度超流体陀螺当前面临的关键问题之一是量程较小,极大地限制了其应用领域.为此,提出了基于全程监测的超流体陀螺量程扩展方法,并设计了实现方案.该方法采用调整其面积矢量方向并在初始时刻注入热相移的技术,避免了超流体陀螺的工作点达到盲点,从而实现对其工作点的全程监测.仿真结果表明,该方法能够有效地解算角速度测量值,使超流体陀螺的测量量程不再受到限制,并且能够判别旋转的极性.
One of the key problems of the new high-precision superfluid gyro currently is its small range, which greatly limits its application field.Therefore, a method based on full monitoring of superfluid gyroscope is proposed and its implementation is designed. By adjusting the direction of the area vector and injecting the thermal phase shift at the initial time, the working point of the superfluid gyro can be avoided to reach the blind spot, so as to realize the full monitoring of its operating point.The simulation results show that this method can effectively solve the angular velocity The measured values make the measurement range of the super-hydro-gyro no longer limited and the polarity of the rotation can be discriminated.
