ASKAP射电天文望远镜伺服控制系统设计

Design on Servo Control System of ASKAP Radio Astronomical Telescope

射电天文望远镜是天文观测和研究的重要设备,澳大利亚平方公里阵探路者(ASKAP)射电天文望远镜是国际天文界正在兴建的新一代射电天文望远镜,针对ASKAP望远镜的观测的需求,设计并测试了一套新的望远镜控制系统,这包括系统硬件设计,控制回路设计,系统软件实现,控制系统电磁电磁屏蔽设计。控制系统设计完成后经过调试,测试结果表明该系统满足望远镜的功能和指标要求。

The radio astronomical telescope is an important device for astronomical observation and research. Australian Square Kilometer Array Pathfinder （ASKAP） radio astronomical telescope is a new generation telescope for radio astronomy. In this paper, a control subsystem was designed and tested for ASKAP, including such designs as hardware, control loop, software and electrical magnetic compatibility for the whole telescope. The test results show that this control system could satisfy the functional and technical requirements. It also passed the electrical magnetic compatibility test.
