【Abstract】 The coupled modal control of structural vibration is studied, and a new control algorithm is presented, in which the physical meaning of the 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 the positions of the control points and measure points have great influence on the control.更多还原
