Active Vibration Control by Piezoelectric Self-sensing Actuator for Beam under a Moving Mass
This research aims at the dynamic response and the active vibration control with piezoelectric self-sensing actuators for the cantilever beam under a moving mass. After analyzing the vibration characteristics of the beam under a moving mass, the active vibration control technology is introduced to suppress its vibration. The dynamic response model and state space model for active vibration control of beam under a moving mass is established. Then the piezoelectric self-sensing actuator sensing signal separation method based on two-dimension adaptive compensating principle is put forward. And the adaptive fuzzy control strategy is introduced to suppress the beam vibration. The testing system of dynamic response and active vibration control for beam under a moving mass is designed and developed. The experimental results showed the effectiveness of this kind of control strategy for beam bonded with piezoelectric self-sensing actuator under a moving mass, which demonstrated that using the smart material could suppress actively the time-varying flexible structure vibration.
