| 摘要: |
| 为使得多枚导弹在存在通信时延的情况下有效完成对机动目标的同时攻击,提出了一种抗通信时延的固定时间收敛分布式协同制导律。该制导律基于固定时间控制技术框架,实现了稳定时间边界不依赖于多导弹系统初始状态,提升了多导弹系统控制效率；采用一种快速非奇异终端滑模和虚拟领弹共同主导的方法,可实现制导律具有对抗通信时延的鲁棒性；利用了李雅普诺夫稳定性理论证明了固定时间内的一致性。仿真结果表明,存在通信时延的情况下,基于所设计的分布式协同制导律,多枚导弹能够有效地完成对目标的同时攻击。 |

| Abstract: |
| In order to make multiple missiles effectively complete the simultaneous attack of maneuvering targets in the presence of communication delay, a fixed-time convergence distributed cooperative guidance law against communication delay was proposed. Based on the framework of fixed time control technology, the guidance law can stabilize the time boundary independent of the initial state of multiple missile system and improved the control efficiency of multiple missile system. A fast non-singular terminal sliding mode and virtual leader were used to realize the guidance law′s robustness against communication delay. The Lyapunov stability theory was used to prove the consistency in fixed time. Simulation results show that under the condition of communication time delay, multiple missiles can effectively attack the target simultaneously based on the designed distributed cooperative guidance law. |
