摘　　要：滚转是弹道导弹的一种新的突防手段,在主动段进行滚动飞行,可以减少强激光照射的驻留时间,有效对抗激光反导。导弹滚转会导致控制耦合、惯性耦合和气动耦合,特别由于采用力矢量合成的操纵方式,俯仰和偏航运动不能独立处理。介绍了滚转弹道导弹的推力矢量控制方式和运动模型,设计了一种具有鲁棒性能的变结构姿态控制系统,得到了有益的结论。The spin is a new method for ballistic missile＇s penetration. It can reduce me awell time of the beam on a particular point of the missile and counter laser antimissile effectively that ballistic missile makes a flight in spinning during the first booster phase. The missile spinning can lead to the couplings of control, inertia and aerodynamics, especially the control mode based on composite of force vectors makes pitch and yaw movements interact. Thrust vector control mode and movement model of spinning ballistic missile were proposed. A robust variable structure attitude control system was designed, and some useful conclusions were drawn.
