Abstract Presently, IR (Infra-Red) detectors are best suitable for spaceborne remote sensing satellites. The IR detectors can be operated at cryogenic temperatures to extract the low-level signal from the background noise. The IR detectors are cooled and controlled at cryogenic temperatures using active cryocoolers. These cryocoolers employed in spaceborne remote sensing satellites generally operate on closed-loop Stirling Cycle. Different variants of these cryocoolers employing linear/rotary motors and Stirling/Pulse Tube cryocoolers have been widely employed in several missions by NASA, ESA, and JAXA. The cryocooler control electronics (CCE) is responsible for providing the drive signal to control the cold-tip temperature keeping vibration exports within desired limits. There is ample literature on control algorithms that help to understand how to control the cold-tip temperature of the cryocooler. Also, various active and passive techniques have been used to reduce the vibration export from the cryocooler. This review paper summarizes different techniques and control algorithms employed in CCE for spaceborne linear cryocoolers. The paper also includes the recent trends practiced in active vibration control to reduce the vibrations of linear cryocoolers used for Onboard and Ground Applications. The control algorithms attract core area of discussion whereas the performance of several techniques has been analyzed with a thoughtful conclusion.

星载线性低温冷却器的控制：综述

摘要 目前，IR（Infra-Red）探测器最适用于星载遥感卫星。IR 检测器可以在低温下运行，以从背景噪声中提取低电平信号。红外探测器使用主动式低温冷却器在低温下进行冷却和控制。这些用于星载遥感卫星的低温冷却器通常在闭环斯特林循环上运行。这些采用线性/旋转电机和斯特林/脉冲管低温冷却器的低温冷却器的不同变体已被 NASA、ESA 和 JAXA 广泛用于多项任务。低温冷却器控制电子设备 (CCE) 负责提供驱动信号以控制冷端温度，将振动输出保持在所需的范围内。有大量关于控制算法的文献有助于理解如何控制低温冷却器的冷端温度。此外，还使用了各种主动和被动技术来减少低温冷却器的振动输出。这篇综述总结了星载线性低温冷却器 CCE 中采用的不同技术和控制算法。该论文还包括在主动振动控制中实践的最新趋势，以减少用于车载和地面应用的线性低温冷却器的振动。控制算法吸引了核心讨论领域，而对几种技术的性能进行了分析，得出了一个深思熟虑的结论。这篇综述总结了星载线性低温冷却器 CCE 中采用的不同技术和控制算法。该论文还包括在主动振动控制中实践的最新趋势，以减少用于车载和地面应用的线性低温冷却器的振动。控制算法吸引了讨论的核心领域，而对几种技术的性能进行了分析，得出了一个深思熟虑的结论。这篇综述总结了星载线性低温冷却器 CCE 中采用的不同技术和控制算法。该论文还包括在主动振动控制中实践的最新趋势，以减少用于车载和地面应用的线性低温冷却器的振动。控制算法吸引了核心讨论领域，而对几种技术的性能进行了分析，得出了一个深思熟虑的结论。
