X-Y座架伺服控制系统的设计分析

Design and Analysis on Servo Control System Based on X-Y Pedestal

为了实现地面站天线对极轨卫星的全程无盲区跟踪,需要解决过顶跟踪问题,分析了天线过顶跟踪盲区的特点,描述了跟踪系统的组成、伺服控制系统的组成、天线控制单元、天线驱动单元、轴角编码单元、安全保护单元等,探讨了基于X-Y(X轴-Y轴)座架过顶跟踪伺服控制系统的坐标转换公式和控制算法。最后给出了系统实际跟踪极轨卫星的跟踪试验结果。

It is necessary to solve the technical problem of vertex tracking so that the earth station antenna can track resource satellite and other special purpose satellite without blind area in the whole course. A design of remote sensing tracking servo control system is presented in this paper, including system operation principle, system composition and system design, The control technique and coordinates tramfonn formula based on remote sensing tracking servo control system. The practical tracking test result is introduced in the end. The engineering practice proves that the vertex tracking servo control system based on X-Y pedestal can realize tracking blind area avoidance in the operating area.
