针对传统末敏弹落点不可控、打击精度不足的问题,提出了一种基于翼伞的末敏弹落点控制技术,采用翼伞代替传统降落伞,实现其落点的精准控制。基于所提出的伞-弹系统,设计了一种基于自抗扰控制技术的伞-弹偏航角精准控制器,并抵消外界风场造成的干扰,弥补末敏弹初始位置误差,实现系统的精准自主操纵。基于上述分析,搭建了伞-弹系统,并进行了实际空投试验。在空投试验中,伞-弹系统的最终落点误差在30 m以内,空中水平最小误差在4 m以内,证明了所提出算法的有效性,为灵巧弹药的设计提供了一种新的思路。

Aiming at the problems of uncontrollable drop point and insufficient strike accuracy of the traditional terminal sensitive projectile, this paper proposes a parafoil based terminal sensitive projectile drop point control technology, which adopts parafoil instead of traditional parachute to achieve accurate control of its drop point. Based on the proposed parafoil-missile system, this paper designs an accurate parafoil-missile yaw angle controller based on active disturbance rejection control technology, which can offset the interference caused by the external wind field and compensate for the initial position error of the non-sensitive missile, so as to achieve accurate autonomous control of the system. Based on the above research content, the parafoil- missile system is built in this paper, and the actual airdrop experiment is carried out. In the experiment of airdrop, the error of the final landing point of the parachute-projectile system is less than 30 meters, and the minimum error of the air level is less than 4 meters, which proves the effectiveness of the proposed algorithm and provides a new idea for the design of smart ammunition in China.
