Passive piezoelectric shunt damping is a vibration suppression method using a piezoelectric element which is electrically shunted by a passive electrical circuit. This paper shows a method of optimizing the values of the elements of the shunt circuits based on the robust performance index against the model uncertainties. For the optimization, the worst-case peak gain of the transfer function is selected as a cost function. From the results of the optimization for the LR shunt circuit, we investigate some required properties for the robustness of shunt circuits. As an example of the robust shunt circuits, the optimization for the LR-LRC shunt circuit is also presented. The experimental results demonstrate the efficiency of the proposed method.
