Abstract
A microcomputer for use with a direct current machine drive system processes machine drive system currents and voltages to compute real time machine efficiency. From real time machine efficiency, the microcomputer determines optimum, that is to say, desired machine armature current and optimum machine air gap flux. Machine armature current and field current are regulated, respectively, by controlling machine armature voltage responsive to the difference in magnitude between optimum armature current and actual armature current, and by controlling machine field voltage responsive to the difference in magnitude between optimum machine air gap flux and actual machine armature flux, respectively, to assure machine operation at maximum efficiency irrespective of machine load conditions.
