ABSTRACT:
A servomotor controlling method and apparatus for use in two inertial systems in which the servomotor and a load are mutually connected by an elastic connection element is provided. A compensation torque value for suppressing oscillation is obtained on the basis of a torque command value for the servomotor and a motor output velocity. The compensation torque value is reflected on the torque command value to then be provided to the servomotor. Accordingly, a resilient torsional torque generated between a driving inertial system and a driven inertial system is properly corrected to thereby suppress oscillation and improve system stability.
