摘要： 在介绍多位置寻北技术原理的基础上，设计一个位置、速度双闭环伺服控制系统，以保证陀螺在转动过程中不受冲击。该系统采用分度定位的方法，在转台一周等间隔选取n个点，通过PID控制器对每点实时进行位置和速度的校正，使各点的转动时间不超过200 ms，定位精度1.1′，实现定向时间短、精度高的方位信息的测量，提高陀螺测量的稳定性，为获得高精度寻北结果提供了保障。

Abstract: In order to prevent the impact in running process, the double loop servo system is designed on the base of the principle of technology of mutiposition north-seeker. The system applys the method of indexing localization, which chooses the equal-space points aroud swivel table. Every point adjusts position and speed of real time by PID controller, the time of running is less than 200 ms and orientation precision is 1.1′. The method realizes short-time and high-accuracy orientation information survey. It is the safeguard for the high- precision results.
