T
he application of the electromagnetoelastic actuator based on the electromagnetoelasticity for the piezoelectric,
piezomagnetic, electrostriction, magnetostriction effects is promising in the nanotechnology, the nano-biology,
the power engineering, the microelectronics and the adaptive optics equipment. The correcting devices are chosen for
providing the high quality of the control systems for the deformation of the piezo actuator. The analytical expressions
for the sufficient absolute stability conditions of the system with the hysteresis nonlinearity of the electromagnetoelastic
actuators are written using the Yakubovich absolute stability criterion with the condition on the derivative, which is the
development of the Popov absolute stability criterion. For the Lyapunov-stable control system, the Yakubovich absolute
stability criterion for the systems with the single hysteresis nonlinearity provides the simplest and pictorial representation
of results of the investigation of the stability and the possibility of the synthesis of the correcting devices of the system
ensuring the stability of the strain control systems with the electromagnetoelastic actuators. The characteristics of the
electromagnetoelastic actuators are the alternating-sign hysteresis type for the piezo actuators and the constant-sign
butterfly type for the electrostriction actuators. In the magnetostriction and electrostriction actuators their initial
operating point is chosen on one wing of the butterfly, for example, in the first quadrant, for the deformation range to be
symmetric at both sides of the initial point. For the butterfly characteristic the initial working point displaced by the half
deformation range. The values of the tangents of the inclination angles of the tangent line to the hysteresis nonlinearity
on the butterfly wing for the electromagnetoelastic actuator are determined similar to the hysteresis characteristic. The
stationary set of the control systems is the segment of the straight line. The absolute stability conditions with the condition
on the derivative of the control systems with piezo actuator deformation in the case of the longitudinal, transverse and
shift piezo effect for the hysteresis characteristic of the deformation of the piezo actuator are obtained. The obtained
absolute stability conditions for the control system with the electromagnetoelastic actuator allow one to estimate and
calculate the characteristics of the control system for the deformation of the electromagnetoelastic actuator.
