为了实现动能拦截直接碰撞目标,分析了反临近空间作战动能拦截器的工作特点和姿/轨控发动机的工作方式;借鉴零控脱靶量原理,设计了一种以轨控发动机开启时间为制导指令的制导律;考虑到拦截器捷联导引头没有稳定平台,设计了姿态控制律,利用姿控发动机实现拦截器的三轴稳定和目标跟踪。仿真结果表明,拦截器能够直接碰撞目标,验证了制导控制算法的有效性。
In order to achieve the goal of kinetic energy interception of direct collision, the working characteristics of anti-Pro / NCEO and the working method of attitude / trajectory control engine are analyzed. Based on the theory of zero-mis-miss distance, a method is proposed that uses the on- Considering that there is no stable platform for the interceptor strapdown seeker, the attitude control law is designed. The attitude control engine is used to realize the three-axis stability and target tracking of the interceptor. The simulation results show that the interceptor can directly collide with the target and verify the effectiveness of the guidance control algorithm.
