弹道导弹滚动飞行稳定仿真

Stability Simulation of the Spinning Ballistic Missile

弹道导弹在助推段需要滚动突防,减少强激光照射的驻留时间,可以有效地对抗激光反导,但姿态稳定的实现则有很大的不同。利用经典控制理论和多变量频域理论设计了导弹的自动驾驶仪,仿真结果表明,对静不稳定导弹的一级助推段可以实现低滚速下的稳定飞行。

To survive the laser's attack, ballistic missiles can spin to reduce the dwell time of the beam at a particular point on the missile. The realzation of stability is different from before. We design the missile's autopilot by the method of classical control theory and MFD technology. The simulation result shows that the unsteady aerodynamic ballistic missile can fly stablly at the low spinning rate during the first boosting phase.
