一种基于滑模非奇异的反舰导弹导引律的设计与仿真

提出了一种反舰导弹滑模非奇异导引律。根据反舰导弹弹道的运动学分析方法，建立了弹目相对运动的数学模型。在非奇异理论的基础上，推导出具有带落角约束的滑模非奇异导引律。通过仿真，表明了该导引律能同时满足脱靶和落角的性能指标，具有优良的鲁棒性，脱靶量更小，精度更高。相比传统的比例导引律，具有更强的实用性和有效性。

Design and Simulation of Anti-Ship Missiles Guidance Law Based on the Non-Singular Sliding Mode

A kind of anti-ship missiles guidance law based on the non-singular sliding mode was proposed in this paper. Based on the kinematics analysis method of anti-ship ballistic missile, the mathematics model of missile target relative motion was established. On the basis of the non-singular theory, guidance law based on the non-singular sliding mode which had the angle constraint was deduced. It was showed that the guidance law could meet performance index of missing target and falling angle at the same time by simulation. The guidance law had excellent robustness. The distance of missing target was smaller, the precision was higher. Compared with the traditional proportional guidance law, it had stronger practicability and effectiveness.
