基于FPGA的潜艇星体跟踪系统.doc

· 1· 摘要: 潜艇星体跟踪系统由工控机集中控制,通过 FPGA 输入角度/ 速度信息,经工控机综合比较和 PID 校正,产生的数字化电压信号经D/A 变换,再经 PW M 及功率放大后控制力矩电机的运动。其软件设计包括:人机交互界面、输入/ 出接口、自动跟踪等程序。该系统可减少潜艇星体跟踪系统所用元件,提高系统可靠性、适时性。关键词: FPGA ;天文导航;星体跟踪中图分类号: 文献标识码: FPGA-Based Submarine Star Tracker System C AO B ing 1,2, CAO Zhong-sheng 1, LIU Ai- don g 2 (1.
