Dynamic analysis and optimal design of a passive and an active piezo-electrical dynamic vibration absorber

Balanced calibration of resonant piezoelectric RL shunts with quasi-static background flexibility correction

“…Piezoelectric transducers are very versatile and may be used as for example actuator/sensor pairs in active control schemes [3,4,5], as semi-active devices based on vari-from [7] has been modified slightly by Yamada et al [24] to exactly follow the procedure used for classic mechanical tuned mass absorbers [22]. Alternatively, it has been demonstrated by Kim et al [5] and Kozlowski et al [25] that the governing equations of the piezoelectric RL shunt circuits are analogous to those of slightly modified mechanical absorber configurations, and calibration expressions have been derived based on these modified models.…”

Laboratory Demonstration Hardware for AVC

“…The xPC Target software prototyping system is a popular choice for the real-time implementation and verification of controllers for AVC both in academic studies and for industrial practitioners [20,28,59,81]. Amongst a few others, dSPACE is also a well-known hardware platform for real-time controller implementation for active vibration control [11,21,24,66].…”

Inverse Task of Vibration Active Reduction of Mechanical Systems

“…The reduction of vibration is related with determining, at a given point of a system, the force with parameters that allow controlling the vibration amplitude of a chosen point in the feedback loop [1][2][3][4][5][6], or utilization in the system socalled energy dissipating components [3,4,[7][8][9]. The values of active and passive components are generated, in systems subjected to vibration reduction, on the basis of information on the dynamic state of the system.…”
