Abstract
A position control system for a closed loop type numerical-controlled machine tool in which detected position information is fed back to the input side from a movable machine part or a motor driving it. In the closed loop there are provided an integrating element and a device for compensating for unstableness of the closed loop caused by the integrating element. The integrating element and the compensating device serve to improve the position deviation characteristic of the closed loop, thereby permitting accurate position control.
