t present the electromagnetoelastic actuators based on the electromagnetoelasticity with piezoelectric, magnetostriction,
piezomagnetic, electrostriction effects are used in the nanonotechnology, the nanobiology, the nanomechanics, the
microelectronics, the adaptive optics and the laser systems. The piezoactuator is the piezomechanical device intended for the
actuation of the mechanisms, the systems or the management based on the piezoelectric effect, converts the electrical signals
into the mechanical movement and the force. The piezoactuator for the nanonotechnology is used in the scanning tunneling
microscopes, the scanning force microscopes and the atomic force microscopes. Using the solutions of the equation of the
electromagnetoelasticity of the wave equation and the matrix equation of the electromagnetoelastic actuator with the Laplace
transform and taking into account the features of the deformations along the coordinate axes, it is possible to construct the
generalized structural-parametric model of the actuator and to describe its dynamic and static properties. Effects of geometric
and physical parameters of electromagnetoelastic actuator and external load on its dynamic characteristics are determined.
Structural-parametric model, decision wave equation and matrix equations of electromagnetoelastic actuator are obtained; its
transfer functions are built. The static and dynamic characteristics of the piezoactuator are determined. For calculation of the
control system for the nanometric movement, the generalized parametric structural schematic diagram and the transfer functions
of the electromagnetoelastic actuator are obtained. The transfer functions and the parametric structural schematic diagram
of the piezoactuator for the transverse, longitudinal, shift piezoelectric effects are obtained from the structural-parametric
model of the piezoactuator. The generalized structural-parametric model of the electromagnetoelastic actuator provides the
determination of its transfer functions and uses the methods of the control theory for the static and dynamic characteristics of the
electromagnetoelastic actuator for nanotechnology. From generalized structural-parametric model of the electromagnetoelastic
actuator after algebraic transformations, we obtained the matrix transfer functions of the actuator.
