为了解决落角控制问题,本文提出了一种新的导引规律。它在零化脱靶量的同时可以达到任何期望的落角。该导引律不需要弹目距离信息和估计飞行剩余时间,并且在理想条件下,对非机动目标可实现完美拦截(零脱靶量和零落角误差)。此外,该导引律可使加速度指令在拦截目标前收敛到零,这有利于加大弹头的侵彻深度。通过与参考文献中两种导引律的仿真对比,表明了本文提出的导引律在落角控制方面的优越性能。
In order to solve the problem of angle control, this paper presents a new guiding law. It achieves any desired drop angle while zeroing off the target. The guidance law does not require projectile distance information and estimation of flight residual time, and under ideal conditions, perfect interception (zero miss and cornering error) can be achieved for non-maneuvering targets. In addition, the guidance law can make the acceleration command converge to zero before intercepting the target, which is beneficial to increase the penetrating depth of warhead. Compared with the simulation of two kinds of guidance law in the reference, the performance of the guidance law presented in this paper is demonstrated.
