摘　　要：研究了动能拦截器轨控发动机的变推力实现方案,重点设计了姿轨控发动机的开关机控制规律,并通过拦截过程仿真,对所设计的控制规律进行了验证。仿真结果表明,姿控系统可以达到很高的角度控制精度,轨控系统可以控制拦截器与目标直接相撞。这说明所设计的姿轨控发动机开关机控制规律是有效的。The variable thrust scheme of the kinetic kill vehicle （KKV） ＇ s orbit control thrustors is introduced and the on-off control laws of KKV＇ s attitude and orbit control thrustors are specifically designed. The designed control laws are proved by the results of interception process simulation. The simulation results indicate that the attitude control system could achieve fairly high angle control precision and the orbit control system could make direct collision between the KKV and the target. These prove the effectiveness of the designed control laws.
