为了适应航天技术的发展和更高的技术要求,设计了一种带闭环控制的单星模拟器。介绍了单星模拟器的工作原理、单星模拟器的光能分析、单星模拟器光源及相关组件的选取、闭环控制系统的设计及星模拟器星等的实现。所设计的星模拟器能够实现对-2~+6星等的模拟,稳定性误差不超过相应星等照度的±10%。检测结果表明,该单星模拟器稳定可靠,调节灵活,能满足单星模拟器设计要求。
In order to adapt to the development of space technology and higher technical requirements, a single-star simulator with closed-loop control is designed. This paper introduces the working principle of single-satellite simulator, the single-star simulator’s light energy analysis, single-simulator light source and related components selection, the design of closed-loop control system and implementation of star simulator. The designed star simulator can simulate -2 ~ + 6 magnitude, the stability error does not exceed ± 10% of the corresponding magnitude illumination. The test results show that the single-satellite simulator is stable and flexible and can be adjusted flexibly to meet the design requirements of the single-satellite simulator.
