Abstract

© 2016 IEEE.This paper presents a direct torque control (DTC) method on a six-phase SRM driven by a six-phase asymmetric half bridge converter. Modeling and simulations of the proposed drive system have been built with MATLAB/SIMULINK. In the proposed DTC method, instantaneous output torque of the six-phase SRM is directly controlled by flux-linkage magnitude and rotating speed regulation (acceleration or deceleration) respective to rotor movement. The simulation and test results accurately reflect the actual operation states of the SRM. Compared with traditional current chopping control (CCC), the DTC method can effectively reduce the torque ripple for the six-phase SRM.
