| 英文摘要 |
| Because of the communication and measurement constraints, when performing persistent target tracking, unmanned
aerial vehicles (UAVs) require a reliable airborne communication relay established by other UAVs to communicate
with the base station. For the purpose of forming the initial airborne communication relay chain, a novel method for cooperative
path planning is proposed to ensure simultaneous arrival of multiple unmanned aerial vehicles (UAVs) with initial
and terminal course angle constraints, which is realized by adopting the minimum turning radius of Dubins curves and appropriately
adjusting the course angle. For the random moving target, establishing continuous reliable communication relay
chain is implemented by using distributed nonlinear model predictive control (NMPC), considering the constraints of UAVs
dynamics, communication constraints, collision avoidance and so on. Simulation results demonstrate the effectiveness of
the proposed method. |
