摘要
论文从工程实践角度探讨了具有大尺寸(直径几米~几十米)和高精度(0.05°)的挠性天线指向控制问题。在借鉴和改进有关抑制挠性天线弹性振动研究的基础上,初步设计了星—地回路的挠性天线指向控制方案。最后,通过分析数值仿真结果,给出了提高挠性天线指向精度的主要因素。
The paper studies the pointing control problem of flexible antenna which has large size(diameter from several meters to tens of meters)and requires high pointing accuracy(0 05°).One of the flexible antenna pointing control method is given in open loop by analyzing and improving the study of elastic vibration suppressing.Finally,after the numerical simulation,the main factors to acquire high antenna pointing accuracy are summarized.
