The resonant shunted piezoelectric has been shown a viable solution for stable vibration control. Two main implementations of the single mode shunt circuit have been developed; the original with a series connection of the resistive and inductive element forming the shunt, and the second, a parallel interconnection, which claimed marginal tuning improvements. More recently, multimodal shunting circuits have been developed where a gain in achievable bandwidth may be viewed as offset by the difficulty in properly tuning. In this paper, the original series shunt formulation is presented in unique detail. Here, the electromechanical analogy is developed, along with a unique technique for accurately tuning the shunt circuit. Experimental results are presented to the theoretical foundations.
