摘要
针对主-从式多飞行器多方位封锁协同打击目标问题,提出三维空间下当从飞行器无导引头时的协同制导方法。主飞行器通过给出的固定时间收敛攻击时间控制制导律实现对目标的指定时间命中,以主飞行器为基准提出球心和半径可动态自调整的目标封锁球面构型函数。以期望封控球面为参考,给出可实现对目标多方位覆盖封锁的同时命中协同制导律,并理论分析该方法的稳定性。仿真结果表明,新提出的方法可实现飞行器群于指定命中时刻同时命中目标,且主飞行器和无导引头的从飞行器可构成对目标的封锁态势。
A three-dimensional cooperative guidance method is presented to investigate the problem of leader and seeker-less follower flight vehicles attacking on the targets by sector coverage.An impact time control guidance law with fixed-time convergence is presented for the leader to reach a target at desired impact time.A sector coverage configuration against target with dynamic self-adjusting center and radius is proposed with the leader as baseline.Finally,on the basis of the desired converge sector,the cooperative guidance law is given for the followers to reach the target simultaneously with multi-directional sector blockade.A theoretical analysis is given to prove the stability of the proposed method.The simulated results show that the proposed method can be used to make all the flight vehicles hit the target at appointed impact time,and the leader and the seeker-less followers can form the coverage situation towards the target.
