Abstract

In direct torque control (DTC) scheme, stator flux vector, and electromagnetic torque are regulated by choosing a voltage vector from a switching logic table. However, the selected voltage vector is not always the perfect one because of only the sector is considered where the flux space vector lies without considering its precise position. Voltage vector selection depends on how precisely the flux is estimated. This paper describes a modified flux estimator scheme for DTC-based induction-motor drives. The flux estimated by the improved flux estimator is used to choose the stator voltage vector in an 18-sector (DTC) flux plane. The proposed control algorithm is comparatively simple and significantly reduces the torque ripple as compared with the basic DTC. Simulation and experimental results proposed algorithm shows the competency of estimator.
