多群组飞行器攻击时间控制协同制导方法

Considering the cooperative guidance problem of multi-master-multi-slave group aircrafts, a cooperative guidance method is proposed which can make multiple groups of vehicles reach the target simultaneously at the desired impact time. Firstly, a cooperative guidance law with impact time control is given for the leaders to achieve simultaneous arrival on basis of the consensus of the time-to-go estimates. After that, the followers in each group with one leader are governed by the proposed cooperative guidance law with the distance consensus. The synchronization of desired impact time for ail the flight vehicles is achieved by means of the consensus of the leader-target ranges and the follower-target ranges. The theoretical analysis indicates that the cooperative guidance laws for the leaders and the followers possess the feature of fixed-time convergence. The simulation results validate the correctness and effectiveness of the proposed approach.
