Abstract
PURPOSE: To improve accuracy in controlling speeds by digitally measuring a actual speed and by computing the difference between the actual speed and a predetermined speed.
CONSTITUTION: An actual speed is computed first by measuring with a pulse counter 25 a total number of speed pulses generated within a certain period of time and with an auxiliary pulse counter 26 a total number of auxiliary pulses generated at a cycle in accordance with the number counted by the counter 25. A speed computer 27 then computes the actual speed depending on the calculated results relative to the speed and auxiliary pulses. Finally, the difference between the actual and predetermined speed is computed by a computer 31 which generates output pulses to operate the accelerator of engines.
