研究了移动刚体激励下弹性发射架的主动振动控制。提出了以梁端振动位移为性能指标和具有末态时刻梁振动为零的末态约束的最优控制方案。用该控制方案进行的仿真计算和模型实验表明，该方案可有效地抑制梁的振动。
The active vibration control of elastic launcher with moving rigid body is studied. The optimal control scheme based on the end-state constraint with the vibration displacement at the beam end as the performance index and the zero moment vibration as the final state is proposed. The simulation calculation and model experiment using this control scheme show that this scheme can effectively restrain the vibration of the beam.
