Active Vibration Control of Piezoelectric Cantilever Beam by the LQR

应用有限元方法建立了贴有压电驱动器的悬臂梁动力学模型,并基于控制目标函数的LQR法,利用Matlab系统仿真,研究了悬臂梁振动主动控制与抑制的问题.最后,提供了数值示例,说明该方法能有效控制悬臂梁的振动.

The application of the finite element method to establish affixed with a piezoelectric cantilever drive model and control based on the objective function LQR of the law,the use of Matlab simulation to study the cantilever vibration control and suppression. Finally,to provide a numerical example to illustrate that the method can effectively control the vibration of the cantilever.
