摘要
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 that the novel high-accuracy superfluid gyroscope is facing is that its measure range is very small, so its applying domain is limited greatly. Therefore, a method for measure range extension of the superfluid gyroscope based on tracing whole pattern is presented, and the imlementation scheme of the method is designed. The method utilizes the technologies of adjusting area vetor direction and injecting thermal phase shift at initial time to avoid working points of superfluid gyroscope reaching blind points, then the working points can be traced whole pattern. Simulation results show that the detecting value of angular velocity can be solved by using the proposed method effectively, the measure range of the superfluid gyroscope is not limited anymore, and the rotational polarity can be distinguished.
