摘要:

研究了多枚导弹同时拦截高机动目标情况下的制导律设计问题。基于终端滑模控制方法和一致性原理设计了多枚导弹协同制导律,实现所有协同导弹的视线角速率在有限时间内收敛到零,视线角收敛到期望的角度。在视线方向上,能够保证多枚导弹具有相同的拦截时间。基于双曲正切函数,所提出的未知上界的在线估计算法有利于减小输入通道的切换增益和抖动。利用Lyapunov稳定性理论,对所设计的闭环系统给出了严格的稳定性证明。在仿真研究中,进一步验证了所提出的协同制导律的有效性。

Abstract:

The problem of cooperative guidance of multiple missiles intercepting a target with higher maneuvering capability is investigated. The proposed cooperative guidance laws, based on the terminal sliding mode control scheme and the consensus protocol, ensure that both the line-of-sight (LOS) angular rates converge to zero and LOS angular converge to the desired angular in finite time. The cooperative guidance laws in LOS guarantee the consensus times to go for all the pursuers. The adaptive algorithm based on hyperbolic tangent function is proposed to decrease the switching gain of the control and the system chattering. The stability of the closed-loop control system is strictly proved using the Lyapunov theory. Numerical simulations are presented to further demonstrate the effectiveness of the proposed cooperative guidance law.
