Direct torque control of switched reluctance motor driven by full bridge power converter

Abstract

A direct torque control (DTC) strategy tailored for switched reluctance motor (SRM) with ring winding structure is proposed. In the proposed topology, stator voltage vectors are reconstructed, and explain the working modes of the SRM. Estimating the reference circulating current by a neural network, that flux magnitude and torque as inputs. With which, ensuring consistent direction of the three-phase winding currents. Circulating current control system and DTC control system of SRM with ring winding structure. Compared the performance of the SRM under various operating conditions in Simulink, validating the effectiveness of the control system.
