一种带落角约束的精确导引方法(英文)

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。

A Method for Precision Missile Guidance with Impact Attitude Angle Constraint

A new guidance law is presented for the impact angle control problem.It can achieve zero miss distance and any desired impact attitude angle simultaneously.The guidance law does not require a time-to-go estimation and information of the range to the target.It attains a perfect intercept(zero miss distance and zero impact angle error) against nonmaneuvering targets under certain ideal conditions.In addition,it is shown that the acceleration command converges to zero at the impact time,which is beneficial to the weapon systems with penetrator warheads.The simulation results show that the new guidance law performs better compared with other two laws from the literatures for the impact angle control problem.
