摘要
分析了天线过顶跟踪出现"盲区"的原因及解决方法。介绍了极轨卫星遥感地面站天线跟踪伺服系统的系统组成、伺服控制系统设计。描述了天线控制单元、天线驱动单元、轴角编码单元和安全保护单元的组成。探讨了坐标转换和控制算法公式等。实际跟踪卫星的结果和仿真计算结果吻合,证实了该控制系统的正确性。
The paper analyzes the factors that cause blindness zone during zenith pass tracking and the solutions,then presents a design of remote sensing tracking servo control system including system operation principle,composition and design,the antenna control unit,antenna drive unit,angle coding unit and security protection unit.This paper discusses the control technique and coordinate transform formula based on remote sensing tracking servo control system.The result of calculation is consistent with the result of experiment.
