Abstract
Abstract—The switching frequency of a conventional direct torque control (DTC) strategy which is based on hysteresis controllers results in a variable switching frequency which depends on the mechanical speed, flux, stator voltage, and the hysteresis band of the comparator. In this paper, a DTC scheme using Space vector modulator (SVM) and fuzzy logic controller (FLC) is suggested. A comparison with the classical DTC is presented. The suggested control strategy guarantees very good dynamic and steady state characteristics with low sampling rate and a constant switching frequency. The simulation results are presented to validate the scheme.
