| 摘 要： | 侧向喷流直接力控制技术已在大气层外动能拦截器和大气层内防空导弹中得到成功应用.运载火箭作为跨大气层飞行器,可以尝试采用该技术进行姿态、轨道控制.介绍了一种由侧向喷流发动机作为姿态控制执行机构的运载器,建立了运载器在大气层外飞行条件下的姿态动力学模型并设计了姿态控制规律.仿真结果表明,在姿控发动机存在安装误差的情况下,所设计的控制规律可以实现对运载器姿态的控制,通过选择控制器参数改变系统的响应特性可以满足迅速、精确、稳定地控制系统的要求.由此可见,采用侧向喷流直接力姿态控制系统能够完成运载器姿态控制任务.

| Abstract: | The direct lateral force technology has been used in ex-atmosphere kinetic-kill vehicle and in the inner-atmosphere air-defense missile successfully.It is possible to control the launch vehicle with direct lateral force when it is flying in the trajectory stages in the atmosphere.A launch vehicle with lateral jet engine as its attitude control mechanism is presented.The attitude dynamic equations of the vehicle when it flying at the altitude above the atmospheric level are established and the attitude contr... |
