固定翼无人机自身携带激光制导导弹进行对地攻击,需要自身携带的光电转台稳定跟踪目标并进行激光照射,指引导弹命中目标;为满足光电转台稳定跟踪目标的角速度限制及导弹可发射的限制条件,设计一种新型的航迹控制算法;利用基于李雅普诺夫向量场的导航算法,实现无人机从盘旋搜索到发现目标后转入导弹可攻击区并实施攻击的自动航迹控制,并保证无人机在调整姿态的同时光电转台稳定跟踪目标;利用某察打型无人机进行飞行验证,结果证明设计的算法能够较好完成无人机的攻击航迹控制,保证导弹发射。
Fixed wing UAV carrying laser guided missile to attack ground target, it needs to keep the photoelectric platiorm tracking the target stably and irradiated continuously. In order to meet the conditions of photoelectric platform and Missiles, design a new algorithm for track control. Using the navigation algorithm based on Lyapunov vector field to realize automatic track control, and keep tracking target stably. The experimental results show that this algorithmis effective.
