摘要
针对空空导弹ENDGAME段,选择合适的导引律,对导弹能否精确打击目标至关重要。本文分析了比例导引律、微分对策导引律和变结构导引律3种不同导引律的设计思路,并引入直接力控制,针对不同攻击条件进行计算机仿真分析。仿真结果表明,在迎击条件下,变结构和微分对策导引律较比例导引律更优,对大机动、持续高速运动的目标,具有直接力控制的制导性能更好。
For the ENDGAME section of air-to-air missiles, it is very important to select an appropriate guidance law for missile to hit targets accurately. This paper analyzes three different guidance laws, that is, the proportional guidance law, the differential game guidance law and the variable structure guidance law. The direct force control is introduced, and then the performance of three different guidance laws under various attack conditions is analyzed by the computer simulation. It is shown that under the engaged condition, the variable structure and the differential game guidance laws are better than the proportional navigation law. For a large motor and sustained high speed targets, the guidance performance will be better with the direct force control.
