Abstract:

In view of the problem of cooperatively encirclement of multiple maneuvering targets by multiple unmanned aerial vehicles (UAVs) under directed communication topologies, a three-dimensional distributed encirclement guidance strategy is proposed. Firstly, by constructing a strongly coupled three-dimensional maneuvering target engagement model incorporating pitch and yaw channels, the proposed method effectively mitigates the guidance performance degradation and addresses the challenges arising from uncertain target maneuvers. Secondly, based on integral sliding-mode control theory and a weighted static optimization method, a distributed cooperative encirclement guidance law driven by a cost function is designed, ensuring optimal allocation of UAV acceleration commands and asymptotic convergence of the system states. Furthermore, the global asymptotic stability of the closed-loop system is rigorously demonstrated through Lyapunov stability theory. Finally, numerical simulation results demonstrate that three UAVs can achieve stable cooperative encirclement of multiple maneuvering targets under a directed communication topology, thereby validate the effectiveness and superiority of the proposed guidance strategy.

Key words: encirclement guidance, maneuvering targets, cooperative guidance, weighted static optimization
