Industrial Automatic Control Systems and Controllers Annotation << Back Transformation of Parametric Structural Schemes of the Piezoactuator of Nanodisplacement under Longitudinal Piezoeffect S.M. Afonin Parametric structural diagrams, structural-parametric model, transfer functions of the piezoactuator of nanodisplays with a longitudinal piezoelectric effect are obtained. The transformation of parametric structural schemes is shown. The structural-parametric model and the parametric structural scheme of the piezoactuator of nanodisplacement with the longitudinal piezoelectric effect based on the wave equation, the Laplace transform, the piezoelectric effect equations are determined. The matrix equation of deformations and transfer functions of the piezoactuator of nanodisplacement are obtained from a system of equations describing its structural-parametric model. The piezoactuator of nanodisplacement under the longitudinal piezoelectric effect is used to compensate for temperature and gravitational deformations in nanotechnology, nanobiology, photonics, power engineering, microelectronics and astronomy. The piezoactuator in the range of displacement up to several micrometers provides the nanometric accuracy of the control system. The infl uence of geometric and physical parameters, external load on its static and dynamic characteristics is studied. The matrix transfer function of the piezoactuator of nanodisplacement with the longitudinal piezoelectric effect is obtained. The transfer functions of the piezoactuator of nanodisplacement fi xed at one end are determined for an elastic-inertial load, taking into account the load mass, the rigiditys of the elastic element and of the piezoactuator.
