ACTIVE VIBRATION CONTROL OF FLEXIBLE STRUCTURE USING PIEZOELECTRIC SENSOR/ACTUATOR

以粘贴有压电传感器／驱动器的柔性梁主动振动控制为例，论述了进行柔性结构传感器／驱动器及控制系统一体化研究的方法。给出了压电传感器的检测方程和驱动器的的驱动方程，以玻璃钢材料的柔性梁为实验对象，并采用自适应滤波技术来实现主动振动控制，控制系统有ＴＭＳ３２０Ｃ２５及４８６计算机组成的主从机系统来实现，实验结果表明此种控制方法是有效的。

This paper presents the integration research on sensor/actuator and control system of flexible structure, and analyses the active vibrational control system of flexible beam system using piezoelectric sensor/actuator.The measurement equation of piezoelectric sensor and the driver equation of actuator are given. An adaptive filtering technique for active vibration control is provided.The control system is realized by the host slave system which consists of computer 486 and TMS320C25. Experimental results have demonstrated the effectiveness of this kind of control strategy.
