摘要
500米口径球面射电望远镜(FAST)是国家"十一·五"立项的国家大科学工程,其控制系统主要包括望远镜总控、主反射面控制和馈源支撑控制三部分。反射面控制是大规模的联动系统的整体控制,本文综合介绍了主反射面控制系统组成、节点位移控制模型和整网控制策略,筛选出多种价值参量,作为建模依据,建立自适应、自学习机制节点位移控制模型,采用开闭环结合控制策略实现反射面高精度实时成型。
Five-hundred-meter Aperture Spherical radio Telescope （FAST） is a Chinese mega science project to build the largest single dish radio telescope in the world. The control system of FAST consists of three sections： the overall control of the telescope, the control of the main active reflector, the control of the Feed cabin suspension system. Control system of the main active reflector is the overall control of the large-scale Linkage system. This article overview the composition of the control system of the main active reflector, the control tactics of the whole network and the control model of the node displacements. The value parameters are selected as the basis of the model. The model of the node displacements is established based on the adaptive and the self-learning mechanism, so the real-time molding of the main active reflector is realized with high accuracy.
