考虑射向位置调节的高超声速滑翔飞行器编队控制方法

Due to the characteristics of hypersonic glide vehicles (HGVs) being unpowered and uncontrollable in axial overload,a significant positional error of HGV often exists at the transition between the gliding phase and the terminal phase, thereby substantially impacting the precision of coordinated strikes during the terminal phase. To address this issue,a formation control method for HGVs is proposed, which considers the capability of adjusting the position in launch direction. Fixed-time consensus controllers are devised for the second-order multi-agent system, serving as the foundation for an underactuated formation control framework. The underactuated control characteristics of HGV formation is analyzed. An adjustment strategy for HGV position in launch direction is formulated, and an analytical relationship between launch-direction position adjustments and additional lateral velocity is established. After enabling the capability for launch-direction adjustment,a three-dimensional artificial potential field is established, and a collision avoidance control strategy for HGV formation is proposed. Theoretical analysis and numerical simulations demonstrate that the proposed method can support the formation and maintenance of a group of HGVs in scenarios such as dispersion,contraction,collective steering,and high and low flying of formation.
