Reusable launch vehicle(RLV) ascent trajectory tracking is realized by flight attitude tracking, the uncertainty of aerodynamic and the thrust cause large deviation of the terminal altitude by open-loop guidance, so a closed-loop guidance is proposed based on feedback linearization.
可重复使用运载器上升段轨迹跟踪是通过姿态跟踪间接实现的,采用开环制导方式,气动或者推力的不确定性可能会导致轨迹末端高度偏差较大,因此研究一种合适的闭环制导方式是非常必要的。
