电基于零控脱靶量的大气层外拦截弹最优中制导律研究
|
摘要
对于大气层外拦截中段自由飞行的弹道导弹,设计了基于零控脱靶量(ZEM)的最优中制导律。在零引力差假设下推导了ZEM解析表达式;基于最优控制理论和庞特里雅金极小值原理,设计了大气层外最优拦截制导律。仿真表明,所设计的制导律能有效实现拦截器中制导段的制导控制,并提高拦截精度。
An optimal guidance law based on zero-effort-miss is proposed for intercepting ballistic missile while it flight in exo-atmospheric midcourse. The analytical expression of zero-effort-miss is derived in case of zero gravitational difference. According to optimal control theory and Pontryagin minimum principle,the optimal midcourse guidance law was designed for exo-atmospheric intercept. Simulation results show that the midcourse guidance law can effectively implement the midcourse guidance of the interceptor,and reduce the miss distance of the interception.
