Abstract

This paper presents a segmented guidance method for multi-UAVs (unmanned aerial vehicles) cooperative attack with spatio-temporal constraints, and successfully implemented in the flight tests. First, the uniform distribution of UAVs around the target is completed through cooperative path planning and tracking in the mid-course phase. The path planning method for cooperative arrival is proposed based on Dubins curve, and the guidance strategy for circular formation flight enables the UAVs to accurately track the reference points which are evenly distributed on the circle. Second, the terminal guidance law in 3D space with impact time cooperation is proposed during the cooperative attack stage, which would further eliminate the accumulated deviation. Finally, simulations and field flight tests for coordinated attack are carried out, which show the effectiveness of the proposed method.
具有时空约束条件的多无人机协同攻击的分段制导方法
本文提出了一种具有时空约束条件的多无人机(UAV)协同攻击分段制导方法,并在飞行试验中成功实现。首先,通过中途阶段的合作路径规划和跟踪,完成无人机在目标周围的均匀分布。提出了基于杜宾斯曲线的协同到达路径规划方法,圆周编队飞行的制导策略使无人机能够精确跟踪圆周上均匀分布的参考点。其次,在协同攻击阶段提出了三维空间冲击时间协同的终端制导法,进一步消除了累积偏差。最后,对协同攻击进行了仿真和实地飞行测试,证明了所提方法的有效性。
