【摘要】：针对飞行器在线轨迹规划问题提出一种基于准平衡滑翔条件的轨迹在线规划方法及利用PID控制器实现的全状态跟踪制导方法。利用准平衡滑翔条件推导了高度、速度及航程等关键参数之间的解析关系,基于此条件结合飞行器当前状态与终端约束实现了物理可实现的滑翔轨迹快速规划;根据需要的速度和高度反馈量设计了PID控制器,实现纵向轨迹跟踪,通过飞行器航向误差走廊保证了飞行航向。仿真算例验证了该方法能实现轨迹在线规划,并对外部偏差具有较强的鲁棒性。
[Abstract]:An online trajectory planning method based on quasi-equilibrium glide condition and a full-state tracking guidance method based on PID controller are proposed for the on-line trajectory planning of aircraft. The analytical relations among the key parameters such as altitude, speed and range are derived by using quasi-equilibrium gliding condition. Based on this condition, the physical and feasible rapid planning of gliding trajectory is realized by combining the current state and terminal constraints of the aircraft. The PID controller is designed according to the required speed and altitude feedback to realize longitudinal trajectory tracking. The flight course is ensured by the flight path error corridor. The simulation results show that the proposed method is robust to the external deviations.
