Motor Control Device and Method for Automatic Adjustment Thereof

Abstract

A motor control device that controls a machine comprising an identification part estimating moment of inertia and viscous friction, a speed command generation part generating a speed command obtained by integrating an acceleration command, a difference signal calculation part calculating a difference signal from the acceleration command with time difference, and an identification interval judgment part determining a valid interval for operate the identification part based on the difference signal, and operating the identification part in the valid interval and driving the motor based on the speed command generated by the speed command generating part, wherein the identification part estimates the moment of inertia and the viscous friction.
