Abstract
A velocity control device controls a velocity of an object via a servo motor so that a damping phenomenon during acceleration or deceleration and a swelling phenomenon of a specified frequency arising at a specified velocity are relieved, while disturbance suppression ability is improved under a wide range of low accelerations. The device comprises an integral gain variable calculation section including an acceleration variable section for calculating an acceleration variable integral gain from an acceleration factor according to an acceleration command value and a reference integral gain and a weighting calculation section for calculating an integral gain from a weighting factor according to a velocity command value, a reference integral gain, and an acceleration variable integral gain. The device may therefore variably set an integral gain according to an acceleration command value and a velocity command value.
