Abstract:

As the unmanned system technology continues to advance, the issue of cross-domain cooperation in unmanned cluster systems has become a research hotspot. To address the problem of front-end cooperative navigation of multi-Unmanned Aerial Vehicles (UAVs) and multi-Unmanned Surface Vehicles (USVs) in a sea-air cooperation scenario, this paper conducts research on the multi-UAVs and multi-USVs formation cooperation mechanism based on the hierarchical leader-follower strategy. A motion model for cross-domain cluster formation is established to describe the leader-follower relationships among various entities within the cross-domain cluster system. Regarding the cooperative trajectory planning problem for the Leader-UAV and Leader-USV, a trajectory cost function considering multiple constraints is formulated based on the established double-layer grid map model. The improved genetic algorithm is employed for optimization. In the context of cross-domain cluster formation cooperative motion control, heterogeneous formation controllers for the leader-UAV and leader-USV and homogeneous formation motion controllers are designed based on the hierarchical leader-follower formation strategy. Parameter tuning is performed for the homogeneous formation motion controller using the fuzzy controller. Simulation experiments validate the effectiveness of the proposed cross-domain cooperative mechanism for multi-UAVs and multi-USVs.

Key words: leader-follower strategy, UAV-USV cooperation, trajectory planning, formation control, fuzzy control
