Zero-Speed Operation of Sensorless Induction Motors Using Full-Order Flux Observer
نویسندگان
چکیده
This paper deals with the flux estimation for sensorless induction motor drives. Stable zerospeed 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 zerospeed operation are shown.
