Abstract :
This paper deals with two different observers for sensorless DTC-controlled induction motor (IM) drives. First is sliding mode observer (SMO), second is extended Kaiman filter (EKF). The main objective of this paper is experimental analysis of limits of these observers and their behavior in challenging low-speed region. Theoretical conclusions presented in this paper are verified by experiments made on designed IM drive prototypes of rated power of 250 W.
