Improved Direct Torque Control for Open-Winding PMSM System Considering Zero-Sequence Current Suppression With Low Switching Frequency

IEEE transactions on power electronics, 2021
This article proposes an improved direct torque control strategy for open-winding permanent magnet synchronous motor (OW-PMSM) with common dc bus for zero-sequence current (ZSC) suppression. The proposed strategy builds a novel voltage vectors (VVs) look-

Direct Torque Control for Induction Motor

2021 International Conference on Digital Age & Technological Advances for Sustainable Development (ICDATA), 2021
The present article discusses the methodology of a Direct Torque and Flux Control (DTC) for induction motor based on six sectors powered by a three-phase two-level voltage inverter. The objective of this paper is to analyze in particular, the duality of the control between the stator flux and the electromagnetic couple using DTC strategy and to confirm

A Reduced Torque Ripple Controller for Direct Torque Control of Induction Machines

Electric Power Components and Systems, 2002
Direct Torque Control (DTC) of induction machines (IM), based on hysteresis comparators and selection table, suffers from variable switching frequency and large torque ripple, especially at low speed. This is because the rate of change of torque and flux and hence the time taken for the torque and flux to reach their upper and lower bands, varies with ...

An Enhanced Model Predictive Direct Torque Control of SRM Drive Based on a Novel Modified Switching Strategy for Low Torque Ripple

IEEE Journal of Emerging and Selected Topics in Power Electronics
The low-cost silicon-made switched reluctance motor (SRM) stands out as a prominent choice for traction motor applications due to its robust rotor structure, fault-tolerance characteristics, lack of permanent magnets, capable speed–torque characteristics,

Design and optimization of a direct torque hysteresis controller

IECON 2014 - 40th Annual Conference of the IEEE Industrial Electronics Society, 2014
In this paper, a direct torque hysteresis controller (DTHC) driving a permanent magnet synchronous machine is discussed. A two-level, three-phase conventional inverter is used as means of power conversion. Advantages such as a low switching frequency as well as further opportunities of the DTHC are specified.

Novel direct-torque-constraint-hysteresis controller

IECON 2013 - 39th Annual Conference of the IEEE Industrial Electronics Society, 2013
A novel hysteresis controller with a direct torque constraint hysteresis (DTCH) shape based on the d-q-coordinate System is presented in this paper. This controller supports the inverter of the drive train system with a bit-pattern. The Inverter drives a permanent magnet synchronous motor (PMSM) by connecting a dc-source, e.g.

IM Direct Torque Control with no flux distortion and no static torque error

ISA Transactions, 2015
The purpose of this paper is to improve DTC control strategy performances. In fact, we propose controlling both stator flux components (real and imaginary) through two hysteresis controllers. Thus, a new switching table which is independent from sector determination, and does not introduce zero voltage vectors is established; with much reduced size ...
