Abstract

China SONG telescope would achieve the goal for long time continuous, uninterrupted, full automatic observation and works in the diffraction limit condition with high tracking precision and reliability, which puts forward a serious challenge to the tracking control system. This paper explores one sliding mode control algorithm to improve the performance of China SONG telescope tracking system. The results show that the algorithm can get higher precision, which has high exploration significance for the telescope tracking system.
