Abstract
Large scale reflecting telescope is a technology-intensive equipment in many fields such as national security, space detection, universe exploration. They are usually equipped with large diameter primary mirrors, which guarantee them with stronger light gathering power and high resolution, to explore instant galaxies from hunderds of millions of light year away. In this context, this talk will firstly introduce the difficulties when designing a hydraulic support system for large scale primary mirrors. Secondly, the supporting stiffness of a hydraulic support system is analyzed. Thirdly, the methodology for the precise position control of a support system shall be discussed. Finally, the future directions with critical research areas in field of hydraulic support system for a primary mirror shall be highlighted.
