Algorithm Study on Active Control of Vibration in Flexible Cantilever Beam Based on Fuzzy Sliding Mode Control

采用压电元件作为传感器和驱动器,基于模糊滑模系统的基本原理,设计了模糊滑模控制器,对挠性悬臂梁进行了主动振动控制。对悬臂梁末端施加控制前后端点的振动响应曲线进行了比较,仿真结果表明,采用的控制器对于提高悬臂梁振动控制是非常有效的。

This paper presents a numerical study concerning on the active vibration control of piezoelectric cantilever beam. By studying fuzzy sliding mode control principle, the fuzzy sliding mode controller is designed, Actuator at the end - point positions is performed in order to investigate their effectiveness to suppress vibrations in intelligent structures. The simulation results show this method can largely supress the vibration, It＇s proved to have a good performance.
