摘  要：为了提高经纬仪的跟踪、捕获、瞄准（ATP）的精度，越来越多的复杂实时算法被应用到光电经纬仪的ATP系统中，因此要求伺服控制器能够在最短的时间内完成大量的运算，即对伺服控制器的运算性能提出了更高的要求。目前的经纬仪伺服系统多是在底板PC104上叠加多种功能板卡来完成捕获跟踪等任务，文章所述系统设计了以嵌入式芯片为核心的伺服系统，增加了可靠性，提高了精度和响应速度。

Abstract: With the rapid development of computer technology,it is widely used in the control field,including cruise missile,radar,O-E theodolite,etc.The increasing complex and real-time arithmetic was applied in the ATP system of O-E theodolite for boosting the track、captring and pointing precision of O-E theodolite,so it demanded the the higher arithmetic function for the servo controller.Designing the servo control system based on embedded chip as CPU from the practicality,decreased the cubage of the system,and increased the reliability and precision.
