摘要: 研究了结构振动主动控制的耦合模态控制法, 提出了一种新的控制律.该控制律设计中所依据的二次型性能指标函数的物理意义十分明确.结合一个实际结构模型进行了振动控制仿真, 由此既证明了本文方法的有效性, 同时也探讨了施控点与测点的选取等问题.

Abstract: The coupled modal control of structural vibration isstudied, and a new control algorithm is presented, in which the physical meaningofthe performance index of the linear Quadratic Regulator(LQR) is very clear.Simulations for the active vibration control of a structural model are carried out.The results show that thepositions of the control points and measure points have great influence on the control.

Key words: structural vibration, active control, mode
