研究火箭导弹初始扰动的主动控制理论和方法 .将火箭导弹发射装置简化为有两点接触的变速运动刚体作用的弹性梁 ,在弹性梁的支承点处施加控制作用 ,提出了基于最优控制理论的控制策略 ,并进行了仿真计算 .仿真结果与分析结果一致 .仿真结果表明所提出的控制策略能够实现对火箭导弹初始扰动的主动控制目的 ,同时表明火箭导弹初始扰动的主动控制是可行的 This paper studies the active control theory and method of rocket missile initial perturbation.The rocket missile launcher is simplified to a flexible beam with two-point contact and the rigid body of variable speed motion is applied to control the supporting point of the elastic beam, and a control theory based on optimal control theory The simulation results show that the proposed control strategy can achieve the active control of the initial disturbance of the rocket missile and the active control of the initial disturbance of the rocket missile is feasible
