Abstract
Damping of vibrations in piezo-electromechanical structures relies on a good design of the related electric networks. The most interesting solutions, from the complexity point of view, make use of two operational amplifiers for each piezo-electric transducer. Although the behavior of such circuits coincides with the ideal controller when the two operational amplifiers are assumed to be ideal, damping and stability issues arise when real active components are used. In this paper, it is shown how the actual performance of these circuits can be improved by modifying the interconnection among components. ©2010 IEEE.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
