摘　　要：采用基于落点预测的方法,对脉冲修正控制进行研究。简化弹道模型;建立脉冲修正控制算法,包括发动机启控条件、选择算法、理想启控方位角和等效脉冲修正力等;以落点偏差为评判依据,分析多因素耦合对脉冲修正效能的影响,包括发动机个数、修正力大小与作用时间、修正阈值及弹体滚转速度等。通过仿真,证明该控制算法是有效的。The correction technique of impulse control force is based on drop-point prediction method. A simple ballistic model is set up and a selection algorithm is proposed. The selection algorithm in- cludes： when to start the impulse engine, how to choose the impulse engine, ideal startup control azimuth model and the equivalent pulse force correction model. The relationship between the multifactor coupling and the correction efficiency of the impulse engine by the miss distance is analyzed. Through analysis and simulation comparison, it is proved that this algorithm is effective.
