Abstract

PURPOSE:To prevent the unsatisfactory revolution of the subject servomotor by a method wherein the output pulse of a fixed width or more is obtained even when an error pulse width is very small by adding the pulse of a fixed width to the output pulse of a pulse-stretching circuit. CONSTITUTION:An input pulse is compared with the pulse of a reference pulse generator 4 using a comparator 4, the error pulse of which is given to the pulse stretching circuit 14 through the intermediary of a dead band circuit 10 and a comparator 12, and the servomotor is controlled through output circuits 16A and 16B. At this time, a pulse adding circuit 20 is added to the output side of the pulse stretching circuit 14, and an output is turned out by adding the pulse of a fixed width, synchronized to the fall of the pulse, to the output pulse. Accordingly, as the pulse with a fixed width or more can be given to the output circuits 16A and 16B even when the width of the error pulse is very small, the unsatisfactory revolution and the unsatisfactory responsiveness of the motor can be improved.
