摘要

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.
