Abstract:

The optical efficiency of satellite optomechanical loads is closely related to thermal design, and model correction of their thermal control system is an essential part of thermal design. In recent years, many reference methods for improving the efficiency and accuracy of thermal model correction based on deep learning and optimization algorithms have emerged both domestically and internationally. However, there is currently no systematic induction. This paper summarizes the new correction methods and focuses on the analysis of several means to improve the correction efficiency in the special problem of satellite optomechanical load thermal control model correction. The means include appropriate optimization algorithm, surrogate model construction and development of automatic correction tools. A specific analysis was conducted on the research progress, applicable conditions, and limitations of these three means, and suggestions were put forward for the development of correction tools. Finally, prospects were made for the field of satellite optomechanical load thermal control model correction, providing direction for improving the accuracy and correction efficiency of thermal models in the future.
