| 摘 要： | 为了改善重复使用运载器末端区域能量管理段的控制系统性能,提出了一种基于轨迹线性化的俯仰角控制回路结构,该结构由伪逆模型前馈和反馈控制组成.根据瞬时平衡的定义,沿轨迹剖面线性化,获得了伪逆模型的设计方法,形成俯仰控制结构.以高空超声速飞行为例,进行了俯仰角控制设计,并与常规反馈控制相比较.结果表明,基于轨迹线性化的俯仰角控制,可以改善控制系统的动态性能,减小反馈回路的负担,降低积分饱和的可能性.

| Abstract: | To improve the performance of terminal area energy management control system for reusable launch vehicle,the pitch attitude control system architecture based on trajectory linearization was developed,which includes two parts: pseudo-inverse model and feedback control system.Using the concept of instantaneous equilibrium,the pseudo-inverse model was designed by trimming the whole profile and the pitch attitude control system architecture was built.Take example for the flight phase of high altitude and super ... |
