On a variable speed control of motors used in industrial plants and industrial robots, a shaft torsional oscillation is often generated when a motor and a load are elastically coupled with a shaft. Such an oscillation may result in damage to the machine.<br>This paper is intended to theoretically explain the fact that a shaft torsional oscillation can be suppressed by using the digital observer regardless of the presense of the gear.<br>In this paper, we conducted tests on two shafts with resonant frequencies at 10.5 Hz and 16 Hz using a full-digital control equipment for controlling DC motors with the digital observer in order to confirm the oscillation control effects.
