Abstract
A system identification device having a position amplitude calculator outputting a position amplifier; a position torque command integral value multiplier outputting a position torque command integral value multiplication value; a position torque command integral value average calculator inputting the position torque command integral value multiplication value and then outputting an average of a position torque command integral value; a speed torque command integral value multiplier outputting a speed torque command integral value multiplication value; a speed torque command integral value average calculator inputting the speed torque command integral value multiplication value and then outputting an average of a speed torque command integral value; and a first inertia moment and viscous friction calculator calculating identification values of inertia moment and viscous friction from the position amplitude, the average of the position torque command integral value and the average of the speed torque command integral value.
