Abstract

PURPOSE:To permit a motor to arrive at a constant speed within a short period of time, by a method wherein the average value of the values of integration terms in a plurality of past normal times is employed as the feedback integration term upon starting the motor. CONSTITUTION:A central processing unit 4 outputs a driving voltage information (y) to a drive circuit 2 based on a proportional factor, operated by a difference between the speed commanding value of a motor and the speed detecting value (v) of the motor 3, as well as an integration term, operated by integrating the difference by time. In this case, the average value Ko of the integration terms in the stationary condition of the rotating speed of the motor, which is achieved in the starting of past N times from the present starting of the motor, is employed as the integration factor upon starting the motor. When the rotating speed of the motor has approached to a speed commanding value, the integration term Kn is obtained in accordance with the difference of the speed. According to this method, the speed of the motor may arrive at a constant speed within a short period of time even when there is fluctuation of a load.
