通过机敏结构建立了三维支架的振动主动控制系统，给出了压电机敏结构的离散控制方程，采用加速度反馈实现了支架的振动主动控制
The vibration-active control system of three-dimensional scaffold is established through the smart structure. The discrete control equation of the piezoelectric vibration-sensitive structure is given. The vibration control of the scaffold is achieved by using the acceleration feedback
