Stator-flux-oriented control of induction motor considering iron loss

Recently, research to consider the Influences of iron loss has been made in the vector control of an induction motor. However, little work has been do ne in the area of a stator-nux-oriented control system of an induction moto r. This paper investigates the effects of iron loss in the direct stator-fl ux-oriented control system of an induction motor, and proposes a control al gorithm considering iron loss. The iron loss is modeled by equivalent iron loss resistance in parallel to the magnetizing inductance, Torque control c apability is much improved and the speed estimation error for a speed-senso rless drive is reduced by the proposed control algorithm, The effectiveness of the proposed method is verified by simulation and experimental results.
