摘要
微重力火箭可以提供一个稳定持久的微重力环境进行一系列科学工程试验,为了达到较高的微重力水平,需要对火箭进行消旋和姿态控制,实现各轴角速度和各向加速度值低于10μG。本文介绍的"yo-yo"系统配合速率控制系统(RCS)可以有效降低各轴角速度和加速度,文章涉及了系统设计参数,控制回路和控制算法等。
Microgravity rockets can support a stable and long microgravity environment to conduct a series of scientific and engineering experiments. To achieve conditions of microgravity above the atmosphere, the rocket need despinning and rate control. This attitude control system provides angular rate control for sounding rocket microgravity payloads to minimize the centrifugal accelerations to a level lower than 10 μG. This article describes the principle of a rate control system. It provides an insight into the interaction between the design parameter, control loop, related algorithm and so on.
