Abstract :
This 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.
