Smart Active Vibration Control System Using Piezoelectric Materials

Vibration suppression has become one of the major issues for modern transportation. The active vibration control of smart structures has received a lot of attention in the field of vibration suppression. A smart active control system comprising of piezoelectric materials, signal conditioning circuits and the embedded hardware is proposed in this paper. The system is featured with self-sensing ability, less components and low-power consumption. A robust controller is designed for this system. The validating experiments show that the proposed smart control system is able to efficiently suppress the modal vibrations.
