Research of Active Vibration Control for Cantilever Beam Based on Macro Fiber Composite Actuators

In this paper, the active vibration control experiment is carried out based on the fast prototype method, and the thin plate cantilever beam is taken as the experimental control object. Firstly, the mathematical model of the controlled object is established. Based on this, the controlled object is evaluated and the control effect of the control method is tested. According to the results of mathematical model simulation analysis, the experimental platform of active vibration control in the form of hardware-in-the-loop is established and simulated in the form of hardware-in-the-loop. The simulation results show that the vibration is suppressed well with the intervention of active control technology. Finally, through the construction of the control experiment platform for physical experiments, it is concluded that under the active control algorithm, the vibration attenuation of the cantilever beam takes 3s from initial vibration to rest, while it takes 30s without control. It can be seen that the active control algorithm has a good effect on vibration suppression.
