| Abstract |
To provide desirable oscillation modes in mechanical systems,
a coordinate feedback is frequently utilized. An influence
of the auto-oscillation-type excitation of a system on the Sommerfeld
effect is considered. The Sommerfeld effect is modeled by
restricted-excitation oscillating systems [1-4]. The conditions
for the existence, stability, and self-excitation of
self-sustained oscillations of a linear oscillator are
analyzed in the first approximation of the averaging method.
The excitation is caused by the inertial forces of an unbalanced
rotor of the electric motor. The derivative of the driving torque
of the motor is defined as a function of the angle of rotation of
the rotor and the displacement of the oscillator.
The parameters providing an autoresonance in the system are determined.
Autoresonance is understood as "a resonance under the action
of a force generated by the motion of the system" [5].
The autoresonance mode in the case under consideration
is shown to be preserved when the parameters
of the oscillator and the motor change. In addition, the oscillation
modes which are unstable when the traditional excitation schemes
are utilized can become stable. |
