Abstract: There is provided a motor control system and motor control method which can shorten settling time by restraining vibration and deviation relative to an advancing direction during operation. Moreover, according to the present invention, it is possible to cause a motor to be operated with an ideal track and, since it is possible to always monitor a present position, it is made easy to cause a plurality of axes to be synchronously operated. The motor control system is provided with a unit generating command waveforms from a jerk data which has significant effects on the vibration relative to the advancing direction, and a unit performing a real time real position control of regenerating future command waveforms according to a deviation amount, while always performing jerk-limit, whereby the vibration and the deviation relative to the advancing direction when the motor operates at high speed are restrained.
