摘要

正确消除飞行器杆臂挠曲运动的不利影响是提高惯导系统传递对准性能的关键技术之一。文中在继承速度积分匹配方法优点的基础上,提出一种平均速度匹配传递对准方案,能够有效降低杆臂的挠曲运动对速度匹配传递对准精度和滤波稳定性的影响。通过在线计算滤波器的系统噪声矩阵Q,避免了飞行器杆臂挠曲运动建模的问题。系统仿真结果表明,该传递对准方案能够提高滤波器的稳定性,并对杆臂挠曲运动进行有效抑制。

Abstract

One of the key to the question of improving the performance of transfer alignment was to remove the negative influence of leverarm flexure correctly. A project of transfer alignment about average velocity matching was proposed to reduce the influence to the accuracy of transfer alignment and the stability of filters effectively, which inherited the advantage of the method about velocity-integral matching. A method of real-time calculating system-noise-matrix was proposed, which avoided the problem of modeling the lever-arm flexure. Simulation results demonstrated that the transfer alignment scheme could increase the stability of Kalman filter, and could also inhibit the influence of the lever-arm flexure effectively.
