Abstract

A RC distributed circuit is proposed in the paper to control vibrations in piezo-electro-mechanical systems. The circuit is designed on the basis of a distributed electro-mechanical model obtained, in particular, for Euler beams. The aim is to achieve mechanical damping while relaxing the constraints on the electrical design. With respect to previous RL approaches, the proposed RC circuit performs better and avoids the use of floating inductors, whose implementation is complex and critical in the stabilization sense. Conversely, even if negative capacitors are necessary, their active realization is simpler and the whole stability of the system can be directly controlled based on explicit constraints derived in the paper.
