摘　　要：佘山13米射电望远镜为新一代天体测量与空间大地测量甚长基线千涉测量(VLBI)系统,在设计之初即提出了方位,俯仰最大旋转速度分别为12%、6%,最大加速度均为3°/s^2,0.001°/S速度引导下不爬行,位置环收敛时间不大于1s等高标准的伺服性能技术指标要求。该观测系统目前正处于联调联试阶段。本文分析了其伺服性能的测试方法,实际采集了测量数据,并实验检验了相应的数据处理方法,所得结果可作为性能评估和优化改进的依据,也可供类似工程测量参考。The Sheshan 13 meter radio telescope is a new generation of very long baseline Interferometry(VLBI)observation system for astrometry and space geodesy,and demanding requirements for servo performance specification are proposed at the beginning of design.To be specific,the maximum slew rates of azimuth and elevation are 12% and 6% respectiverly;the maximum acceleration in both directions is 3°/s;there well be no scrambling behavior at the minimum slew rate of 0.0013°/s^2 and the setup time is no longer than Is.The telescope is currently in the phase of joint commissioning.In this paper,servo performance tests and observations of the telescope are analyzed,and the results can be used as a basis for performance evaluation and optimization,and a reference for similar engineering surveying.
