Abstract :
Direct torque control (DTC) of an Permanent Magnet Synchronous Motor(PMSM) fed by a Voltage Source Inverter(VSI) is a novel scheme that exhibits improved performance of PMSM drive. In the proposed DTC, the selection of voltage vector is achieved by the application of torque error, flux error and sectors. In this scheme, the estimated and reference flux value is obtained from the reference and estimated value of electromagnetic torque. A better drive performance can be achieved by varying the duty ratio of the selected voltage vector during each switching period according to the magnitude of the torque error and position of the stator flux.
