卫星控制系统全物理仿真

Physical Simulation for Satellite Control Systems

仿真是应用相似定理和类比关系来研究事物 ,也就是用模型代替实际系统进行实验和研究。在卫星控制系统仿真中 ,根据所介入的模型的不同 ,分为数学仿真和物理仿真两类。卫星控制系统全物理仿真是研制卫星过程中特有的一种仿真方法 ,它利用气浮台作为运动模拟器 ,又称为气浮台仿真。本文主要叙述卫星控制系统全物理仿真的原理和用途 ,简要介绍单轴气浮台和三轴气浮台两个全物理仿真系统的组成。

Simulation is a research method adopting similarity theory and analogical relationship, using model instead of real system. It can be classified as mathematical simulation and physical simulation. Physical simulation is used to verify the design of control system in the process of satellite development. Because air-bearing table is the dynamic simulator, physical simulation is also called air-bearing table simulation. This Paper presents principle and application of physical simulation for satellite’s control systems.This paper briefly introduces two physical simulation systems including system constitution and technical performance of their primary devices. At the same time, this paper provides several physical simulation examples for satellite control systems.
