A charge controller for linear operation of a piezoelectric stack actuator
IEEE Transactions on Control Systems Technology, 2005This paper examines the position control problem of piezoelectric stack actuators and presents a method for overcoming the hysteresis nonlinearity between the applied voltage and the actuator displacement. An inverting charge control circuit is implemented to linearize the stack actuator movement by taking advantage of the linear relationship between ...

Compact piezoelectric stacked actuators for high power applications
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2000Small, hollow, multilayer actuators with a diameter of 3 mm were fabricated by the stacking method from piezoelectric hard lead zirconate titanate (PZT) ceramics. Langevin vibrators were also constructed with the hollow multilayer actuators. The performance capabilities of the actuator and Langevin vibrator samples were examined under high-power ...

Ultrafast Displacement Actuation of Piezoelectric Stacks With Time-Sequence
IEEE Transactions on Industrial Electronics, 2017Driving a piezoelectric stack with fast response and high output force is critical for its application. A novel ultrafast time-sequence driving method for piezoelectric stacks that could be used in fuel injectors is described and demonstrated. This technique is shown capable of reducing the response time of a piezoelectric stack by considering the ...

Design and test of a novel piezoelectric stack pump
Proceedings of the 2010 Symposium on Piezoelectricity, Acoustic Waves and Device Applications, 2010The 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 ...

A discrete piezoelectric stack absorber model
2001Mechanical 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.
