弹性发射梁振动的主动控制及实验研究

ACTIVE VIBRATION CONTROL AND EXPERIMENTATION OF FLEXIBLE LAUNCHING BEAM

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 a flexible launching beam activated by amoving rigid body is studied. An optimal control strategy is proposed with the displacement of the beam end as the performance index and with the restriction of zerovibration at the terminal time. The simulation and the experimental results showthat the control strategy can efficiently suppress the vibration of the beam activatedby a moving rigid body.
