Self-powered semi-passive vibration damping system based on the self-sensing approach

Bidirectional energy‐controlled piezoelectric shunt damping technology and its vibration attenuation performance

“…Finally, the experimental results confirmed the feasibility and demonstrated the vibration control performance. Shen et al 18 implemented a self-powered SSDI circuit on the basis of the so-called self-sensing technology; the switching control signal based on zero-velocity crossing detection 19,20 was obtained by properly processing the voltage from the piezoelectric actuator, which was also used for vibration damping synchronously, and the optimal switching time without delay was then achieved.…”
