摘要：

This paper proposes a new sensorless vector control method for induction motors using a minimum dimensional flux D-state observer with instantaneous speed estimation. First, the D-state observer with a new design rule of constant observer gains is established in a different way. Second, a new speed estimator using flux estimates produced by the observer is established on the basis of the fundamental relationship between the rotor flux and the slip frequency. Speed estimates are reused in the observer as feedback. Characteristic analyses and the usefulness of the proposed vector control method are verified by simulations. (C) 2016 Wiley Periodicals, Inc.
