应用现代控制理论研究战术导弹控制规律的文献已有很多,它们大都是按确定性控制系统来讨论的。由于忽略了目标随机机动及其它随机干扰因素,所以对半主动寻的地空导弹的控制系统,通常的制导规律并不是十分令人满意的。本文的目的是为设计半主动寻的地空导弹数字控制系统而研究的随机最优制导规律。数字计算的结果表明,数字控制系统可以采用这种制导规律,在目标有随机机动等情况下,能使终端脱靶量达到最小。因为系统中配有相应的弹载计算机,使实现这种制导规律成为可能。
There are many literatures about the tactics of tactical missile control using modern control theory. Most of them are discussed according to the deterministic control system. Due to the neglect of the target random maneuver and other random disturbances, the usual guidance law is not very satisfactory for the control system of semi-active ground-to-air missile. The purpose of this paper is to study the stochastic optimal guidance law for the design of semi-active ground-to-air missile digital control system. The numerical results show that the digital control system can use this guidance law, in the case of a random target, can make the terminal miss distance to a minimum. Because the system is equipped with a corresponding on-board computer, to make it possible to achieve this guidance.
