The paper describes a reliable modeling technique for piezoelectric transducers and a procedure for identifying model parameters with few simple measurements and standard laboratory equipment. For validation purposes, the behavior of the equivalent electromechanical circuits was simulated and compared to direct observations in real operating conditions. The model showed to predict with a high degree of accuracy both the frequency response of the transducers and the effects due to the presence of non-linear power converters which are usually ignored by conventional models presented in literature.

Abstract
The paper describes a reliable modeling technique for piezoelectric transducers and a procedure for identifying model parameters with few simple measurements and standard laboratory equipment. For validation purposes, the behavior of the equivalent electromechanical circuits was simulated and compared to direct observations in real operating conditions. The model showed to predict with a high degree of accuracy both the frequency response of the transducers and the effects due to the presence of non-linear power converters which are usually ignored by conventional models presented in literature.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
