Abstract:

To improve the target capture capability of unmanned aerial vehicle (UAV) in uncertain environments and the efficiency of multi-UAVs collaborative searching, the proposed method named improved co-evolutionary genetic algorithm (ICEGA) based on dual attribute probability maps is proposed for multi-UAVs cooperative target capturing. Firstly, according to the prior information of the environment, the flag bit is introduced to the original probability map, and the proposed environment probability model is built. Secondly, the flight rules of UAVs and the environment probability model are used together to establish the UAV motion model and the objective function. Finally, the distributed model between the UAVs is established, and the ICEGA algorithm is used to optimize the input heading angles set with cooperative decision-making. The experimental results show that the dual-attribute probability map working with the ICEGA algorithm can guarantee the optimal searching path, so that the UAV can accurately capture the target. At the same time, the comparable experiments prove that the ICEGA algorithm can improve the coordination between UAVs, make the flying path feasible and improve the efficiency of target capturing.
