Control of characteristics of mechatronic systems using piezoelectric materials

Andrzej Buchacz, Marek Płaczek, Andrzej Wróbel
This paper presents two examples of systems with piezoelectric transducers used in order to control vibration. First of them is a combination of a single piezoelectric plate glued on a mechanical subsystem surface. The piezoelectric plate is applied to suppress vibration of the system. The second model consists of a few piezoelectric plates vibrating in a thickness mode. Such kind of systems is called the piezostack and is used to enhance the transducers sensitivity or to increase the displacement. In both cases, characteristics of the considered systems were generated and presented on charts.
