A fuzzy logic, energy optimizing controller has been developed to improve the efficiency of motor/drive combinations which operate at varying load and speed conditions. The energy optimizer is complemented by a sensorless speed controller which maintains motor shaft revolutions per minute (RPM) to produce constant output power. Efficiency gains of from 1 to 20% are obtained from laboratory demonstration with commercial motors and drives. Motor shaft RPM is controlled to within 0.5%. The energy optimizing controller used for vector control adjustable speed drives is complemented by a torque pulsation control scheme to rapidly damp vibrations.
