研究了关于具有压电式传感器 (Sensor)和调节器 (Actuator)的板振动的能动控制 ,并用有限元素的方法预测了面板的动态响应。该系统由于模型的误差可能导致溢振 (spillover) ,从而需用具有鲁棒性的 H∞ 控制方法来抑制板的振动。实验证明 ,这种控制方法是有效的。
The dynamic control of plate vibration with piezoelectric sensor and Actuator was studied and the dynamic response of the panel was predicted by finite element method. The system may cause spillover due to model errors, so the H∞ control method with robustness is required to suppress the plate vibration. Experiments show that this control method is effective.
