| 摘 要： | 研究采用共位配置的分布式压电敏感器和致动器的挠性悬臂梁的振动控制问题，其中敏感器由压电聚乙二烯氟化物薄膜（PVDF）制成，致动器由压电陶瓷（PZT）或PVDF制成。本文首先建立系统的模型，设计了一种线性反馈控制方案，并应用无穷维空间的LaSalle不变原理，证明了相应闭环系统的渐近稳定性。

| Abstract: | This paper analyses the vibration control of a flexible cantilever beam with collocated piezoelectric sensors and actuators being the layers msde of piezoelectric ceramic (PZT)and piezoelectric polyvinylidene fluoride fluoride (PVDF), presents the system model and designs a linear feedback control law. By using LaSalle's invariance principle in infinite dimensional space, we show that implementation of the control algorinthm results in asymptotical stability of the closea loop system. |
