基于状态反馈控制的柔性臂系统振动抑制

Vibration Suppression of Flexible Arm Based on State Feedback Control

以典型的挠性结构———柔性臂为研究对象,建立了柔性臂系统的分布参数模型,在柔性臂上粘贴压电陶瓷片作为传感器和致动器,将分布参数模型转化为集中参数模型,最后针对柔性臂系统设计了状态反馈控制器。实验研究结果表明,柔性臂的低阶振动得到了很好的抑制。

A flexible arm with some piezoelectric sensor and actuators was investigated to find a way to control the vibration of flexible structures. The distributed parameter model for this beam was established first. Then, the model was transformed into a set to lumped parameter models. A state feedback controller was used to suppress the vibration of the flexible arm. The experiment results show that the low-order vibration is well controlled.
