The telescope drive control system provides essential power support for the successful execution of astronomical observations, and its reliability directly impacts the efficiency of these observations. This paper focuses on strategies for enhancing the reliability of the telescope drive control system, proposing a comprehensive and multidimensional reliability improvement solution. The study examines mechanisms for enhancing reliability from three perspectives: expected fault diagnosis, unanticipated state identification, and reliability optimization during the design phase. For each of these aspects, specific reliability enhancement solutions are proposed, including a fault diagnosis and self-healing expert system, a generic process model for unanticipated state identification, and an optimized tracking control strategy under timestamp synchronization. Furthermore, the paper demonstrates the feasibility of these solutions from the three aforementioned perspectives, providing a clear direction for the development of reliability enhancement strategies for telescopes.
