为解决在末制导阶段引入直接力控制的时机问题,提出了一种基于模糊规则的设计方法。文中以应用广泛的比例导引律为基础,将剩余时间、目标机动、导弹需用过载、导弹速度这四个影响直接力引入时间的因素综合考虑,对直接力引入时机进行分析,利用模糊规则将四者综合,得到直接力引入时机。通过数字仿真,验证了该设计方法能够有效解决在末制导阶段直接力引入时机问题。

A design method based on fuzzy rules was proposed for solving the problem of searching the beginning time of direct jet in terminal guidance phase. In order to getting the beginning time of direct jet, based on proportional navigation, fuzzy rules were used to synthesize four factors: left time, target maneuver, commanded lateral acceleration and speed of missile. The computer simulation results prove that the method is efficient.
