The invention provides an under-actuated non-minimum phase RLV attitude control method based on a dynamic sliding mode, which can realize accurate tracking control of longitudinal and lateral attitudes only by using two movable flaps of an RLV, stabilize a sideslip angle to be zero, and solve the problem of under-actuated non-minimum phase control in an RLV reentry process. The control design is relatively simple, and the method has certain robustness for system state and parameter changes.

    本发明提出一种基于动态滑模的欠驱动非最小相位RLV姿态控制方法,所述方法可以仅利用RLV的两个可动襟翼,实现纵向和侧向姿态精确跟踪控制的同时,将侧滑角镇定为零,解决RLV再入过程的欠驱动非最小相位控制难题。控制设计较为简单,且对于系统状态和参数变化具有一定的鲁棒性。
