Abstract

In this paper we solve the problem of finding an optimal passive electrical controller of beam vibrations exploiting distributed piezoelectric transducers. To this aim an electrical circuit analog to a Euler beam is synthesized using a Lagrangian method and by paralleling capacitive flux linkages to rotations and transverse displacements. Therefore a piezo-electromechanical (PEM) beam is conceived by uniformly distributing piezoelectric transducers on a beam and interconnecting their electrical terminals via the found analog circuit, completed with suitable resistors. The high-performance features of the synthesized novel circuit include: i) the circuit topology is extremely reduced, the used components are all but one two-terminal passive elements, and the' only two-port network needed is an ideal transformer; ii) one and the same dissipative circuit assures a multi-resonance coupling with the vibrating beam and the optimal electrical dissipation of mechanical vibration energy.
