Control strategies and algorithms for large astronomical optical telescope

This paper gives a summary on control strategies and algorithms for contemporary large astronomical optical telescopes. The study lays emphasis on high precision tracking for large astronomical optical telescopes with large inertia, ultra-low speed and multi-disturbance. The control strategies and algorithms of some telescopes based on direct drive or friction drive are analyzed carefully. Finally, the future development in this field is presented.
