Abstract
A common motor drive configuration is the field-oriented controller with a pulse-width-modulated inverter. The controller has a digital processor and analog current regulator. Common forms of the current regulator have both steady state errors which degrade the field orientation and a suboptimal modulation scheme which produces excessive losses in the inverter. These deficiencies may be improved by digital processing
