ABSTRACT:
The control device is provided with a frequency converter for feeding electric power to an induction motor and a compensating circuit for compensating for the delay of the response of the field flux to a control target value. The second transfer function of the compensating circuit is selected such that the resultant of the first transfer function of the field flux with respect to a control target and the second transfer function would be a constant.
