| 摘 要： | 针对500 m口径球面射电望远镜(Five-hundred-meter Aperture Spherical Telescope)1∶15密云缩尺模型馈源支撑系统进行仿真建模。分析密云模型馈源支撑控制系统的结构组成和控制方式,并在MATLAB、Simulink环境中建立仿真模型。仿真模型主要包括三个模块:弹簧阻尼器模块、A—B转台和Stewart平台,这些平台通过PID控制器进行控制。密云模型和仿真模型运行同一个天文轨迹,通过分析运行结果显示仿真模型控制性能与密云实际模型相似并且满足望远镜的指向精度要求。

| Abstract: | A simulation model of the feed support system for the 1:15 down-scaled model of the Five-hundred-meter Aperture Spherical Telescope (FAST) in Miyun Observation Station is proposed in this paper. The structure of the feed support control system is illustrated. The simulation model is built in MATLAB, Simulink with three modules: the spring and damper module, A-B rotator and Stewart platform which are all controlled by PID controllers. Both the Miyun model and the simulation model run the same astronomical observation track. After analyzing the output data of these two models, the results show that the performance of the simulation model is similar to the Miyun model and satisfies the pointing accuracy requirement. |
