Abstract
PURPOSE:To permit shifting from starting operation to stationary operation without causing overshoot, by a method wherein a control time point, whereat the difference of acceleration, generated upon shifting from the starting operation to constant speed operation, is made zero, and a speed setting value upon the time point are calculated. CONSTITUTION:At first, a time point TM whereat a speed formula Ves(t) upon starting operation coincides with the speed formula Vcs(t) is operated. Subsequently, an acceleration upon stationary operation at the time point TM is obtained. The speed formula upon starting operation is corrected based on said acceleration upon the time point TN so that the difference of accelerations, generated upon shifting from the starting operation to the stationary operation, becomes zero, thereafter, the speed formula V'es(t) is operated. Then, the speed of a motor is controlled based on the speed formula V'es(t). According to this method, the starting operation may be shifted to the stationary operation without causing any overshoot.
