Description:
The report discusses the development of a fuzzy logic, energy-optimizing controller to improve the efficiency of motor/drive combinations that operate at varying loads and speeds. his energy optimizer is complemented by a sensorless speed controller that maintains motor shaft revolutions per minute (rpm) to produce constant output power. fficiency gains of from 1 to 20% are obtained from laboratory demonstration with commercial motors and drives. otor shaft rpm is controlled to within 0.5%. he energy optimizing controller used for "vector control" adjustable speed drives is complemented by a torque pulsation control scheme to rapidly vibrations.
