Abstract

The part load efficiency of induction motor can be improved by adjusting the motor excitation in accordance with load and speed. For the speed control of induction motor drives under part load, adjustment of stator flux is done by the controllers that obtain stator currents and speed as feedback signals. This method of improving efficiency during part load by flux adjustment is called energy optimal control and the present paper investigates the effects of sensor faults in energy optimal controlled induction motor drives.
