Design and test of a novel piezoelectric stack pump

Proceedings of the 2010 Symposium on Piezoelectricity, Acoustic Waves and Device Applications, 2010
The structural design, the working principle and the performance of a novel piezoelectric-hydraulic pump driven by piezoelectric stack are introduced. A steady-state dynamic model of the piezoelectric pump system was established. The electrical/mechanical/fluid coupling behaviors of the pump system were taken into consideration in the dynamic model ...

Linear motor using stacked piezoelectric ceramics

2011 International Conference on Electronics, Communications and Control (ICECC), 2011
To meet the need of advanced manufacturing technology, a piezoelectric actuator with high resolution was developed in this work. The principle of exciting the driving tip to vibrate elliptically was analyzed in detail. A prototype was fabricated to validate the analysis.

A discrete piezoelectric stack absorber model

2001
Mechanical absorbers are sometimes used to reduce vibration levels on structures that are subjected to narrow band dynamic excitation. However, active control systems have in recent years received a great deal of attention and can be very effective. They are however costly.

Modeling and Control of Piezoelectric Stack Actuators with Hysteresis

2013
Piezoelectric actuators are popularly applied as actuators in high precision systems due to their small displacement resolution, fast response and simple construction. However, the hysteresis nonlinear behavior limits the dynamic modeling and tracking control of piezoelectric actuators.
