Paper Abstract

The Chinese ever-ambitious project of 30 meter-class telescope, Chinese Future Giant Telescope (CFGT), has brought about an extraordinary challenge for the control system's robustness. Various severe factors that we have never experienced before, will impact on our considerations for the control system. With the practice in our ongoing LAMOST project plus an investigation and a reasonable prediction the paper tries to deal with, at very preliminary stage, the control system configuration in general and a number of extreme difficulties in particular, such as the drive system and analysis of wind torque disturbance rejection, etc.
