基于滑模控制的双约束条件下协同制导律的设计

Cooperative Guidance Law Design Based on Sliding Mode Control with Impact Time and Terminal Angle Constraints

针对多枚导弹打击同一目标的问题,进行协同制导律的设计。采用了能实现有限时间收敛的终端滑模控制法,既能满足攻击时间约束,又能实现期望的末端角度,并用李雅普诺夫稳定性理论证明了所得到的结果。最后通过仿真验证了提出的制导律的有效性。

In this paper, a missile cooperative guidance law was designed to solve the problem of multiple missiles hit ring the same target. With the terminal angle and impact time as constraints, a finite time convergence sliding mode control method was used to obtain the missile guidance law. The obtained result was proved by Lyapunov stability theory. A simulation was conducted and the results verified the effectiveness of the proposed method.
