基于ARM的空间光通信APT控制系统设计

Design of APT System in Space Optical Communication Based on ARM Processor

设计一种基于ARM嵌入式处理器为核心的控制系统,该系统主要完成在空间无线光通信中信标光的扫描、捕获和跟踪控制,即APT控制系统。以光栅螺旋扫描算法实现信标光的扫描、捕获功能,用增量式PID控制算法实现信标光的跟踪控制功能。该设计具有高实时性、高集成度、低功耗等优点,可满足空间光通信中APT控制部分的要求。

APT system in space optical communication based on embedded ARM processor is designed. The scanning, acquisition and tacking （APT）control of beacon is implemented by adopting raster helix scan algorithm and incremental PID algorithm. This design features a high real - time index,high concentration degree and a low power level,which are all very appropriate to an APT system.
