摘要: 随着无人机应用越来越广泛,空间中无人机密度迅速增加,防碰撞控制技术成为无人机实现安全飞行的重要保证。本文首先建立了多无人机协同感知与防碰撞系统结构,针对编队中无人机数量较少的情况,基于模型预测控制提出了一种速度可变的多无人机协同防碰撞方法,当无人机数量较大时,采用群智能规则设计一种速度恒定的多无人机协同防碰撞方法。数值仿真结果表明,模型预测控制方法具有较高的控制精度,群智能方法则具有较好的实时性。

Abstract: With the wide application of unmanned aerial vehicles(UAVs), the UAV density in the space has increased rapidly, and collision avoidance control technology has become an important guarantee that UAVs can fly safely. Firstly, a multi-UAVs cooperative sense and collision avoidance system structure is built. Then, a novel cooperative collision avoidance method based on the model predictive control(MPC) is put forward aimed at a small number of UAVs. Finally,another cooperative collision avoidance method based on the swarm intelligence rules is proposed when the number of UAVs is big enough. Simulation results demonstrate the MPC method has higher control precision and the swarm intelligence method has better real-time.
