ABSTRACT:
A method for operating a DC motor controller according to a first gain when the armature current of the DC motor is discontinuous, according to a second gain when the armature current is continuous, and according to a third gain when the armature current is in transition from the discontinuous to continuous conduction. The gains have proportional and integral terms and the integral term in the discontinuous and transition regions varies inversely to a current reference in the controller.
