Antarctic telescopes, especially those located at Dome A, face significant reliability challenges owing to the extremely harsh working environment, among which the reliability of the control system is critical in ensuring stable operation. This paper describes various factors affecting the reliability of Antarctic telescopes, as well as the challenges of reliability improvement. Combined with the development of Antarctic telescopes and the experience of Antarctic scientific expeditions, we introduce, in detail, the optimization strategy for reliability enhancement, including the hardware layer, software layer, modular design to facilitate maintenance, and reliability management. The current status of the Antarctic Survey Telescope (AST3) is also briefly introduced, along with future development plans. We aim to provide ideas for the reliability design of Antarctic telescopes and provide technical support for the development of future Antarctic telescopes.
