| Abstract: | Firstly,the vibration characters of Timoshenko beam which mounted by PZT were analyzed and a simple model for it was given. Then the vibration modes were analyzed based on this simple model. At last a control system using the neural network method was presented,and the characteristics of the system were simulated numerically by MATLAB. |
| Keywords: | Timoshenko beam modal control active control |
