Abstract
This paper deals with the flux estimation for sensorless induction motor drives. Stable zero-speed operation is achieved by using a speed-adaptive full-order flux observer and a simple software compensation of inverter nonlinearities. No voltage feedback is needed for the compensation and hardware costs can be lowered. Experimental results including stable zero-speed operation are shown.
