Time coordination and formation control techniques for hypersonic gliding vehicles: A survey

<p indent="0mm">With the significant improvement of anti-missile interception capability, the effectiveness of a single gliding hypersonic vehicle is gradually reduced. As an effective way to break the constraints, the research value and strategic significance of multi-aircraft high-speed cooperation have attracted more and more attention. On the one hand, multiple aircrafts reach the target at the same time through time cooperative control, so that the interception system can reach saturation and achieve effective penetration. On the other hand, during the flight process, multiple aircrafts perform more abundant tasks such as cooperative detection through formation flight. In this paper, two typical cooperative modes of time cooperative control and formation control of gliding hypersonic vehicles are summarized. Firstly, the application of trajectory planning, cooperative guidance, deep learning and reinforcement learning in time cooperative control is analyzed at the algorithm level. Secondly, the three core technologies of formation maintenance, formation reconstruction and communication optimization in formation control are analyzed in depth. Finally, the future development direction and research trend of time cooperation and formation control technology of gliding hypersonic vehicles are prospected.
