ABSTRACT:
A position control system has a motor for moving a movable member which is driven, at first, by a non-controlled signal. Responsive to a position error signal which represents a difference between a present position and a commanded position, and to a velocity signal which represents a velocity of the movable member, a deceleration signal is generated for positioning the movable member at the commanded position. When it exceeds a predetermined level, the deceleration signal is applied to the motor, instead of the non-controlled signal.
