| 摘 要： | 提出一种利用压电薄膜片对弹性连杆机构的动力响应主动控制方法，推导了粘结压电材料后机构的有限元方程。应用模态控制理论对弹性连杆机构振动主动控制问题的原理和策略进行研究，给出了相应最优控制律。在此基础上研究了采用比例微分控制器达到模态最优控制的效果时，其增益参数的确定方法。

| Abstract: | A control method for suppressing the elastodynamic responses of elastic linkage mechanism is presented using piezoelectric actuators and sensors in the paper.The FEM formulations of the linkage bonded with the piezoelectric films(PVDF) are derived.Also, the model control theory is used to study the theory and strategy of active vibration control problem of elastic mechanism vibration with the correspondent optimal control equations given.Based on above study,determining the actual control gain while the optimal model effect isobtained with the proportional differential controller is discussed.Numerical simulation is performed to evaluate the improvement of elastodynamic response of a four bar mechanism. |
