Abstract
A servo control system has a first integrator to which the speed of a servomotor is fed back and a second integrator to which the speed of a mechanical load of low rigidity is fed back. The speed of the servomotor and the speed of the mechanical load driven by the servomotor are simultaneously reflected at a prescribed ratio on a transfer function of the servo control system, whereby appropriate servo control is made possible for the mechanical load to achieve speed control having a quick response and stability.
