| 摘 要： | 从理论和实验两方面研究了基于行波模型的结构梁响应控制方法。在梁及压电陶瓷作动器等处采用行波理论模型,导出了抑制柔性梁中行波传播的主动控制律及相应的控制补偿器。这是一个具有超越函数的补偿器．并在100～300Hz的中频段,根据近似拟合的补偿器进行了主动控制实验研究,实验结果达到了50％的良好的控制效果。

| Abstract: | An active control method based on a flexural propagating wave model for a long and thin beam with a piezoceramic actuator is investigated both analytically and experimentally.The control law of suppressing the transmission of the propagating waves in the beam and a formula descriping the compensator of the control system are derived by using the propagating wave model of the beam,including in the region of the beam where a piezoceramic actuator is attached.An experiment in active control is performed.In the experiment the compensator is simulated by an anolog computer which approximately fits the derived compensator formula in a range of frequency between 100 Hz and 300 Hz.Experiment results show that a fairly good effect is achieved with a 50% reduction in the disturbed amplitude. |
