Research on active vibration control of cantilever beam based on active damping device

A regulating technique is presented and designed in the active vibration control of a cantilever beam in this paper. An active damping device(inertial actuator) is proposed and designed. A control system for the constructed inertial actuator is developed. The dynamic model of the cantilever beam system with the constructed inertial actuator system is established and analyzed. A PID controller is designed and analyzed. An experimental platform of the cantilever beam system is constructed to verify the effect of the inertial actuator and efficiency of the control algorithm. Experiments have shown that the vibration of the cantilever beam with the active damping device is significantly reduced, and the vibration decreased by approximately 50% compared to the original cantilever beam system.
