| 摘 要： | 研究了压电智能结构振动控制问题。采用基于分支电路的主动-被动混合的控制方法对结构振动进行抑制，通过在控制器中设置主动电感使得分支电路的谐振频率在一定范围内可以连续调节，以适应激励频率的变化。给出了系统的模型及控制算法，并进行了仿真及实验研究。仿真及实验研究的结果表明该方法能有效地抑制结构振动，并且其鲁棒性明显好于Filter-x算法。

| Abstract: | The vibration control for piezoelectric smart structure is studied. Active-Passive Hybrid method using shunted circuit is used to suppress structural vibration. An active inductance is included in the controller to make the resonant frequency of shunted circuit be tuned continuously within a certain range. This can adapt to the variation of the excitation frequency. The system model is given and the control algorithm is derived. Computer simulations and experimentations are carried out, simulation and Experimental results show that this scheme is able to suppress structural vibration effectively and has better robust performance than Fihered-X algorithm. |
