Abstract

This paper focuses on the space vector modulation (SVM) strategy applied to direct torque control (DTC) to overcome the high ripples content in torque and improve the speed response using hybrid fuzzy-PI controller. A key feature of DTC is its ability to control electromagnetic torque in direct by proper selection of voltage vectors. In DTC-SVM, the division of six sectors of stator flux gives only limited control over the voltage vector. So, further division of the stator flux locus from six sectors to twelve sectors is proposed here which leads to better choice of voltage vector. Unlike conventional DTC-SVM, a more advanced fuzzy-PI controller is introduced with the DTC-SVM in place of the hysteresis torque controller to reduce the ripple content in torque. So a novel strategy for the selection of optimum voltage vector from a hybrid fuzzy logic (FL) controller is developed here which has the flux locus divided into twelve sectors would achieve minimized torque ripple and improved speed response.
