摘要
针对超视距舰空导弹拦截低空飞行的目标时,会导致在制导初段就出现导弹"掉海"的现象,提出一种虚拟目标的设计方法,并利用伪控制量的概念,应用线性二次型最优控制理论,设计了一种最优导引律。仿真结果表明,虚拟目标设计方法具有良好效果,所研制的最优导引律是可行的。
The ship-to-air missile could drop into the sea at the beginning of the midcourse guidance,when the target flights in the low altitude beyond visual range.Towards to this phenomenon,the method of the virtual target was presented to perfectly solve the problem.Applying the concept of the pseudo control variable and the theory of the linear quadratic optimal control,an optimal guidance law was designed.The simulation results show that the method of the virtual target has better effect and the designed optimal guidance law is feasible.
