Abstract

Based on an unconventional design concept the LAMOST telescope will become the world's most powerful meter-class level ground astronomical optical survey telescope when it is completed. From technical perspective the goal with such a high profile has brought an extraordinary challenge to its control system. For better image quality the telescope's segmented reflecting Schmidt mirror has to be actively controlled by nanometer technique. At the same time the mirror is driven on both azimuth and altitude axes in subarcsecond accuracy for tracking the star. Vigorous study has been done and a number of cutting edge techniques are applied to meet the tough requirements. This paper gives the overview of LAMOST control system, outlines its distributed, real time, reliable and expansible configuration and the simulation approach. The current status of the control system is briefly reported in this paper too.
