Abstract
The vibration propagation and active control of power flow in finite connected plate structure are studied. The dynamic response of the connected plate is obtained by the wave approach. The active power flow at the junction of the connected plate is suppressed by the feedforward active vibration control. It indicates that the active power flow at the junction of the connected plate cannot be well suppressed by the optimal control force for minimizing the acceleration, but it can be effectively suppressed by the optimal control force for minimizing the active power flow. The small error of the optimal control force has slight effects on the control results.
