On the robustness of negative-C R shunt circuit for piezoelectric shunt damping system with parasitic resistance

Abstract

In piezoelectric shunt damping, which is one of sensorless damping techniques, various problems arise due to the parasitic resistance of the piezoelectric element when using a negative-C R shunt circuit. In this paper, we consider the robustness of the shunt damping system against variations in the parasitic resistance.
