| 摘 要： | 为了实现500 m 口径球面射电望远镜（Five-hundred-meter Aperture Spherical radio Telescope, FAST）的高精度指向观测，对柔性基础上的馈源舱控制精度进行了系统研究。通过轻量化高刚度的结构设计、运动与控制联合仿真、半实物仿真试验以及现场调试等措施，保证了馈源舱的动力学性能。通过 AB 轴和Stewart 组成的二次调整装置，采用大范围、高精度和高采样率的测量控制技术实现了馈源舱在百米大尺度空间内，克服高空风扰、钢索振动及自身的运动耦合等影响，将馈源定位于瞬时焦点。

| Abstract: | In order to realize the high precision pointing observation of the five-hundred-meter aperture spherical radio telescope (FAST), the control accuracy of the feed cabin on the flexible foundation is systematically studied. The dynamic performance of the feed cabin is ensured through the measures such as lightweight and high rigidity structural design, joint simulation of motion and control, semi-physical simulation experiment and on-site testing. Through the secondary adjustment device composed of AB axis and Stewart, the large scale, high precision, high sampling rate measurement control technology is adopted to realize that the feed cabin can overcome the influence of high altitude wind disturbance, cable vibration and its own kinematic coupling in a large scale space of 100 meters, and locate the feed source at the instantaneous focus. |
