研究利用压电主动构件实现智能桁架结构阻尼控制的技术．控制方法采用局部积分力反馈，将压电主动构件的弹性内力经积分器反馈，以此获得施加于压电主动构件上的驱动电压，达到智能桁架结构闭环阻尼控制的目的．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控制实验，结果表明，该控制方法是有效的，可获得较大的结构模态阻尼．
The technology of using piezoelectric active components to realize damping control of intelligent truss structure is studied. The control method adopts the feedback of local integral force to feedback the elastic internal force of the piezoelectric active component through the integrator to obtain the driving voltage applied to the piezoelectric active component to achieve the closed-loop damping control of the intelligent truss structure. This control method has good stability and robustness. Through a space truss structure control experiment, the results show that the control method is effective, can obtain greater structural modal damping.
