Flare longitudinal control for approach and landing of reusable launch vehicle

  • 摘要: 针对可重复使用飞行器(RLV)进场着陆拉平段的纵向控制问题,提出了反馈控制与前馈控制相结合的复合控制策略。设计反馈控制律参数,在此基础上基于时间加权高度跟踪误差/误差变化率平方积分指标优化设计前馈控制律参数。按输入补偿的前馈控制在不影响系统稳定性的前提下,提高了RLV对拉平着陆轨迹的跟踪精度,减小了RLV的接地散布。提出了基于积分器初值的控制律平滑切换方法,实现了RLV起落架释放前后不同控制律之间的平滑切换。仿真验证了拉平纵向复合控制和拉平过程中不同控制律之间平滑切换方法的有效性。
