Vibration Control of a Mechanical Structure with Piezoelectric Actuators - a Comparison of Bimorph and Stack Actuators
The practical results of the vibration suppression of a cantilever beam with a low voltage piezoelectric bimorph patch and a stack actuator are discussed. After the equation of motion of the controlled system is obtained by the finite element method, a modal analysis is performed to reduce the numbers of degrees of freedom. A modal linear quadratic feedback controller is realized on a real-time...
متن کاملTransverse and longitudinal dynamic modeling of bimorph piezoelectric actuators with investigating the effect of vibrational modes
Bimorph piezoelectric cantilevered (BPC) actuators have recently received a great deal of attention in a variety of micro-electromechanical systems (MEMS) applications. Dynamic modeling of such actuators needs to be improved in order to enhance the control performance. Previous works have usually taken transv...
متن کاملFPGA-Based Control of Piezoelectric Actuators
Abstract: In many industrial applications like semiconductor production and optical inspection systems, the availability of positioning systems capable to follow trajectory paths in the range of several centimetres, featuring at the same time a nanometre-range precision, is demanding. Pure piezoelectric stages and standard positioning systems with motor and spindle are not able to meet such req...
متن کاملPiezoelectric Bimorph Cantilever for Vibration-Producing-Hydrogen
A device composed of a piezoelectric bimorph cantilever and a water electrolysis device was fabricated to realize piezoelectrochemical hydrogen production. The obvious output of the hydrogen and oxygen through application of a mechanical vibration of ~0.07 N and ~46.2 Hz was observed. This method provides a cost-effective, recyclable, environment-friendly and simple way to directly split water ...
متن کاملAn Inversion Based Model Predictive Control on Piezoelectric Actuators
Hysteresis is an important nonlinear effect exhibited by piezoelectric actuators and its control has been drawing considerable attention. This paper presents the development of an inversion based model predictive control to compensate for piezoelectric actuator hysteresis. Experiments were carried out to verify the effectiveness of the developed control method. The result obtained shows that th...
