This paper proposes a cooperative path-planning method based on multi-Dubins path segments to meet the penetration requirements of UAVs in a complex threat environment. A pruning strategy is used in path-planning to sift path segments, and the diversity of threat avoidance paths is considered under a reasonable calculation amount. A threat intrusion strategy is designed for no safety path condition, which makes the cooperative path-planning method have excellent robustness. A cooperative path optimization method based on particle swarm optimization is adopted for the path length and collision avoidance requirements. The simulation results show that the UAV cooperative paths can avoid the threat area under any starting and ending points, and path lengths are close to the expected length.

Under the condition of strong connectivity, the formation keeping problem of missile formation based on high-order fully actuated system is studied. The time-varying controller of the system is designed for the formation tracking of missile formation and disturbance suppression by upgrading the first-order model to the second-order model and using the parametric approach. The numerical simulation experiments of the system are completed with the introduction of bounded random disturbances. The motion trajectory, position tracking error, velocity tracking error and control force output of the missile formation are analyzed, and the final steady-state error is basically stabilized within 0.1, and the control force is controlled at about 2000 N during the formation holding phase.
