This paper compares three commonly used system identification methods applied to test data derived from two separate thermal vacuum tests and a multi-loop measurement.

文章选取两次航天器热真空试验、多个回路实际测量数据,通过比较常见的3种辨识方法的辨识效果,认为相对于其它两种辨识方法,近似极大似然递推算法具有抗干扰能力强、适应不同噪声环境、参数稳定收敛等优点。

In this paper,a method for thermal design and calculation of infrared heating cage in thermal vacuum test is described,which introduces the concept of"valid radiation"to design and calculate the function of heating cage.

文章介绍了一种航天器热真空试验用红外加热笼热设计计算的方法,提出了利用"有效辐射"的概念进行热设计计算的一般方法,并结合一次试验,进行了加热笼热设计计算的验证。

Low temperature environment is simulated by using a cascade refrigeration system in the thermal vacuum test facility of spacecraft subassembly.
