A motor control system suppresses vibration of a machine base and achieves high-speed positioning without using a special sensor but using a model control system. A first feedback section outputs a first feedback command generated based on model machine base position information and containing at least position information on the machine base. A second feedback section outputs a second feedback command containing a filtered model torque command. A differential between the sum of the first feedback command and the second feedback command obtained by a second addition section and the model torque command is calculated to give the differential to an input portion of a model torque command low-pass filter and an input portion of a torque command low-pass filter. The model control system gives a model position command to a position controller as a position command, and model machine base position information generated based on the model position command is added to a speed command input from the position controller to a speed controller.
