Abstract
A current controller has provided therein assumed response generating means and load model means so as to realize repetitive type control with no influence of control delay against a periodically repetitive current response. This current controller is applied to a 120-degree current flow type motor using a pulse width modulation inverter, so that the DC current control including the process of response to the rise of the current can be realized only by a microcomputer.
