PURPOSE:To obtain a stable control performance by providing a current model and a speed model and adding a deviation between each model output and actual current and speed as a compensating element to a current command. CONSTITUTION:A speed control circuit 1 compares a speed command Nr with a speed detection value Nf to output a current command Ic. A current model 10 outputs a model current value IM according to the current command Ic and a speed model 11 outputs a model speed NM according to the model current value IM. A deviation epsilonI between the output IM of the current model 10 and an actual current detection value If is outputted as a current correction signal II and a deviation epsilonN between the output NM of the speed model 11 and the actual speed detection value Nf, as a current command correction signal IN. An addtion circuit 2 adds a current command Ic and the current command correction signals IN, II to output a current command Ir to a current control circuit 3. |
