Abstract
This brief paper proposes a novel impedance structure for piezoelectric shunt damping. The impedance has a highly resonant nature and can be considered as a feedback controller applying a high gain at each resonance frequency of the base structure. Closed-loop stability of the system is proved and robustness properties of the associated controller are studied. Experimental results, demonstrating the effectiveness of the proposed procedure are presented.
