MOTOR SPEED CONTROLLER

摘要

PURPOSE:To remarkably improve the controlling characteristic of a motor speed controller by eliminating the occurrence of a time lag when the rotating speed of a motor is changed. CONSTITUTION:The value corresponding to the torque required for accelerating or decelerating a motor 5 is found by differentiating the output of a speed command generation means 1 by means of a differentiation means 7. Since the torque required for accelerating or decelerating the motor 5 can be generated without relying on a feedback loop by adding the output of a comparison means 3 to the found result in a feed-forward state by using an addition means 8 at the input section of a motor drive circuit 4, the controlling characteristic of this motor speed controller can be remarkably improved.
