چکیده انگلیسی مقاله:
Abstract- A torque control scheme, based on a direct torque control (DTC) algorithm using a 12-sided polygonal voltage space vector, is proposed for a variable speed control of an open-end induction motor drive. The conventional DTC scheme uses a stator ?ux vector for the sector identi?cation and then the switching vector to control stator ?ux and torque. However, the proposed DTC scheme selects switching vectors based on the sector information of the estimated fundamental stator voltage vector and its relative position with respect to the stator ?ux vector. The fundamental stator voltage estimation is based on the steady-state model of IM and the synchronous frequency of operation is derived from the computed stator ?ux using a low-pass ?lter technique. The proposed DTC scheme utilizes the exact positions of the fundamental stator voltage vector and stator ?ux vector to select the optimal switching vector for fast control of torque with small variation of stator ?ux within the hysteresis band. The present DTC scheme allows full load torque control with fast transient response to very low speeds of operation, with reduced switching frequency variation. Extensive experimental results are presented to show the fast torque control for speed of operation from zero to rated.
