This paper proposes new methods which improve the robustness and the performance of the passive vibration suppression using piezoelectric elements applying the dual-inductance circuit. Two types of methods which use two inductances were proposed in this paper. Because the electrical systems of new methods have two resonances, they could solve the problems of the performance and the robustness which had not been done by previous methods. Optimum values of the circuit were derived both with and without considering the variation of the stiffness of the main system. The effectiveness of new methods and the optimum values of the circuit were verified by calculation and experiment.
