加速度计在非陀螺寻北系统中的应用研究

Application Study of a Accelerometer in Nongyroscopic North Seeking System

根据加速度计及基于哥氏效应的加速度计动态寻北系统的工作原理,探讨了加速度计在该系统中特殊的应用方法:测量地球自转的北向分量、转台机械安装的倾斜角和电机的旋转速度。研究结果表明:巧妙地将加速度计应用于寻北系统中,充分发挥惯性元件的自身特点,可提高寻北系统的定位精度,对传统伺服系统的改造,也有借鉴意义。

In the accelerometer dynamic north seeking system, the special application methods of the accelerometer were discussed based on the accelerometer theory and the working mechanism of the system. The specific uses include measuring the north component of the earth spin rate, the slant angle of the gimbal and the motor speed. The study results show that the orientation precision of the north seeking is improved by applying the accelerometer to a north seeking system skillfully and making use of its characteristics fully. The paper has the referenced meanings for the reconstruction of the conventional servo system.
