Model predictive control-based direct torque control for matrix converter-fed induction motor with reduced torque ripple

CES Transactions on Electrical Machines and Systems, 2021
To reduce the torque ripple in motors resulting from the use of conventional direct torque control (DTC), a model predictive control (MPC)-based DTC strategy for a direct matrix converter-fed induction motor is proposed in this paper.

A direct torque control for a PMSM

2010 20th International Conference on Electronics Communications and Computers (CONIELECOMP), 2010
For a long time, permanent magnet synchronous motors (PMSM) were only applied in some particular fields, e.g. for servo drives. However, in recent years PMSM gained increasing importance in novel domains like automotive hybrid drive trains [1]. For Mexico, this boom represents a valuable opportunity for universities and research institutions, so that ...

New torque and flux controllers for direct torque control of induction machines

The Fifth International Conference on Power Electronics and Drive Systems, 2003. PEDS 2003., 2004
This paper presents the implementation of a high performance direct torque control (DTC) of induction machines drive. DTC has two major problems, namely, high torque ripple and variable switching frequency. In order to solve these problems, this paper proposed a pair of torque and flux controllers to replace the hysteresis-based controllers. The design

Examination and Linearization of Torque Control System for Direct Torque Controlled IPMSM

2008 IEEE Industry Applications Society Annual Meeting, 2008
This paper examines the torque response based on direct torque control (DTC) for an interior permanent magnet synchronous motor (IPMSM). DTC with a PI controller for torque control is used in this study. The relationship between the gains of the PI controller and the torque response is derived based on the transfer function of the torque control loop ...

An Optimal Controller Based-on GA for Direct Torque Control

2009 Third International Conference on Genetic and Evolutionary Computing, 2009
In direct torque control (DTC) of induction motor, the performance of system is influenced by the given value of torque. The given torque is the output of speed regulator. And PID adjustor is used generally as the speed regulator, so the selection of PID parameters is crucial to DTC system.

Modeling of a new torque controller for direct torque control of induction machines

2000 TENCON Proceedings. Intelligent Systems and Technologies for the New Millennium (Cat. No.00CH37119), 2002
In this paper a new torque controller for direct torque control (DTC) of induction motor drives is proposed. The structure of the new controller is very simple with its output similar to that of the conventional three level hysteresis comparator. The approximate frequency domain model of the proposed controller is presented which served as a guide for ...

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 ...

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.

ABB: Direct torque control

Industrial Robot: An International Journal, 1995
Examines the development of a powerful AC variable speed drive technology that is reported to offer the best performance yet from an AC drive, allowing it to match and even better the performance of DC motor drives. The technology is called direct torque control [DTC] and uses motor flux and torque as primary control variables.
