| Abstract: |
| Based on the optimal control theory, an active vibration control method of smart structures has been researched. In this research, the scaling function transformation of the wavelets has been adopted; sensors and actuators are also designed. Finally some largespacetrussstructures have been taken as illustrated examples, and some digital simulations have been made. The numerical results show that the control method is effective. |
