Series-Parallel Impedance Structure for Piezoelectric Vibration Damping

摘要

This paper introduces a passive piezoelectric shunt controller, for damping multiple modes of a. flexible structure using one piezoelectric transducer. The series-parallel impedance structure has a number of advantages over to previous techniques; it is simpler to implement, requires less passive elements and contains smaller inductors values. The vibration control strategy is validated through experimental work on a piezoelectric laminated cantilever structure.
