一种攻击海面小型机动目标的高精度导引律

A high-precision guidance law for attacking small maneuvering target on the sea

针对海面小型导弹快艇高速、机动性强的特点,应用李雅普诺夫稳定性理论设计一种新的高精度导弹平面导引律。对于目标的运动信息,通过估算的方法获取。数学仿真结果表明,在考虑导弹动态特性时,如果不对导弹动态特性进行补偿则很容易导致脱靶,而对导弹动态特性用动态逆的方法进行动态补偿后,则可显著提高导弹命中目标的精度。仿真试验证明了该导引律的有效性。

Lyapunov stability theory is used to design a new yaw plane guidance law for missile against small yacht, which have high-speed and maneuverability on the sea. An estimation method is given for getting the information of yacht. The mathematic simulation results show that if the dynamic characteristic of missile is compensated, it is very easy to miss the target if the compensation method is unconsidered, but the accuracy of hitting target can be greatly improved if the dynamic characteristic of missile is com- pensated with the dynamic inversion approach. Simulation results prove the effectiveness of the guidance law.
