基于直接侧向力控制的智能末导引律的设计与仿真

提出了一种适用于末段直接侧向力控制导弹的智能制导律．制导律的设计采用比例＋Bang Bang的组合制导形式，具体方案是在末段直接侧向力控制启动之前采用比例导引，在直接侧向力控制启动之后，根据直接力控制的非线性特点，采用Bang Bang制导．直接侧向力启动时间的确定非常重要，提前或者延迟启动直接侧向力都会大大影响导弹的制导精度．为了确定直接侧向力的启动时间，提出了一种智能模糊算法来确定具体的直接侧向力启动时刻，仿真结果表明，该制导律在对付大机动的目标时能取得较好的制导精度，可以满足直接命中的要求.

Design and Simulation of an Intelligent Terminal Guidance Law Based on Direct Lateral Jet Control

Based on direct lateral jet control, an intelligent terminal guidance law is proposed. Direct lateral jet control can change missile's trajectory quickly, so the time to start direct lateral jet is very important, high guidance precision can be obtained only if we start direct lateral jet at a certain time. In order to obtain the time, an intelligent terminal guidance law is proposed.We can get appropriate start time by fuzzy reasoning, and the simulation results show the proposed intelligent guidance law can achieve high guidance precision when the target maneuvers with high acceleration.
