基于变结构控制的前向拦截导引方法

A Head Pursuit Guidance Scheme Based on Variable Structure Control

对于来袭的高速大机动弹道导弹特别是洲际弹道导弹,由于其速度很高,应用常规的尾追式或迎击式拦截方式,对拦截弹的速度、机动性、准确性都有更高的要求,所以难度较大,为此产生了一种新型的前向拦截导引方法,设计了一种基于变结构控制的前向拦截导引律,它具有导引精度高、需求过载小等优点,数字仿真验证了所给方法的有效性。

Maneuverable ballistic missiles, especially inter continental ballistic missiles usually have high speed, so the interceptors have to need much greater capabilities in speed, maneuverability and accuracy if they intercept the targets under the condition of stem chase or head on attack. Because of these difficulties, a novel head-pursuit law appears, and the law based on variable structure control is presented. It has many merits of high accuracy and low lateral overload, and is proved by numerical simulations.
