摘要
研究利用压电主动构件实现智能桁架结构振动阻尼控制的技术。控制策略采用局部积分力和局部速度复合反馈,将测量的压电主动构件弹性内力和两端节点的相对速度,经控制器放大复合后得到压电主动构件的驱动电压,实现智能桁架结构阻尼控制的目的。这种控制方法具有良好的稳定性和鲁棒性。通过一个空间桁架结构的振动阻尼控制实验,结果表明该控制方法是有效的。
This paper presents a new method for active damping control of intelligent truss structures using a piezoelectric active member by a local integral force and velocity feedback. The feedback control law has good stability and robustness, in which the active member is controlled with the compounded integral force and velocity feedback on the voltage applied to it. Control experiments are conducted on a space truss structure to show that the presented method is very effective in damping vibration response of the structure.
