摘要
针对固体运载器耗尽关机的制导问题,提出一种基于零控拦截流型的耗尽关机制导方法。在闭路制导阶段,考虑目标和运载器存在引力加速度差时,基于零控拦截流型推导一种显示的制导方法,该制导方法形式简单,制导精度高,通用性强。在能量管理阶段,设计适用于零控拦截流型下的能量耗散管理方法,该制导方法降低了能量耗散末段姿态剧烈抖动,又保证了运载器处于零控拦截流型上。通过仿真表明,该耗尽关机制导方法能够保证运载器在关机时刻处于零控拦截流型之上,并高精度命中目标。
Considering the issues of depleted shutdown guidance of solid carrier,a depleted shutdown guidance method based on zero-effort interception state is proposed.In the closed-loop guidance stage,considering the gravitational acceleration difference of the target and carry,a display-guided method based on zero-effort interception state is deduced.It is a simple,high guidance precision,versatility guidance method.In the energy management stage,the energy management strategy is designed to apply to the zero-effort interception state.It reduces the severe jitter in the end of energy management and also ensures the carry is on the zero-effort interception state.The simulation shows that the depleted shutdown guidance method ensures the shutdown time is above zero-effort interception state and high-precision hitting the target.
