| Abstract: | The linear quadratic regulator(LQR) method,in which the vibration energy of the structure and the energy of the control signal are considered in the objective function,is adopted to control the vibration of the plates with various boundary conditions by using piezoelectric material.The effects of the size and position of the piezoelectric flat on the vibration control are studied by simulation experiment.Several basic views about optimizing the size and position of the piezoelectric flat are given. |

| Keywords: | piezoelectric intelligent plate vibration control LQR method energy criterion |
