一种半球谐振陀螺仪周向漂移快速校准技术OA
A Rapid Calibration Technique for Circumferential Drift in Hemispherical Resonator Gyroscopes
半球谐振陀螺仪凭借高精度、轻小型化等技术特点,逐渐在制导装备、航空航天领域推广应用,然而半球谐振陀螺仪在长期使用过程中,其周向漂移会随着谐振子性能的变化而改变,进而影响使用精度,因此需要定期对其进行校准.为提升半球谐振陀螺仪精度保持能力,本文基于半球谐振陀螺仪误差模型,提出了一种针对周向漂移的快速校准方法,通过虚拟旋转的方法,实现周向漂移和虚拟旋转误差的有效分离.经仿真和试验验证,校准后的标准差达到0.112 4(°)/h,校准时间仅需大约326 s.
Hemispherical resonant gyroscopes(HRGs),characterized by high precision,miniaturization,and light weight design,have been increasingly deployed in guid equipments,aerospace,and other fields.However,during long-term operation of HRGs,circumferential bias drift varies with resonator performance,thereby affecting operational accuracy.Therefore,HRGs require regular calibration.To improve accuracy retention,this paper proposes a fast calibration method for circumferential bias based on the HRG error model.The circumferential zero offset and virtual-rotation error are effectively separated via virtual rotation.Through simulations and experimental verification,the standard deviation of residuals after calibration is 0.112 4(°)/h,and the calibration time is merely 326 s.
