Abstract
A heating system for the mechanical shutter for the Antarctic Bright Stars Survey Telescope (BSST) is introduced. The system consists of a thermal insulation shutter house and a heating control box. The key design of the thermal-insulation shutter house is introduced. The heating control algorithm based on fuzzy-proportional–integral–derivative is designed to improve the performance of the system. A secure control algorithm for power MOSFET is necessary in extremely cold environments. The system has been tested in the cryogenic environment for 4 weeks, which proved that the heating system has the characteristics of low temperature adaption, high accuracy of the temperature control, remote operation, and detection. As a part of the BSST, the system has been running successfully for over half a year at Zhongshan Station, Antarctica.
