Torque Ripple Minimization for Induction Motor Drives with Direct Torque Control

Electric Power Components and Systems, 2004
Direct torque control (DTC) schemes can produce quick and robust responses, but they usually behave like hysteresis controllers. Consequently there are similar problems like non constant switching frequencies and high torque ripple especially when operation conditions result in low switching frequencies.

An Improved Model Predictive Direct Torque Control Strategy for Reducing Harmonic Currents and Torque Ripples of Five-Phase Permanent Magnet Synchronous Motors

IEEE transactions on industrial electronics (1982. Print), 2019
Five-phase permanent magnet synchronous motors offer merits of high fault tolerant capability and high torque per rms ampere and, thus, are suitable for applications, such as aerospace and electric vehicles.

A new direct torque control strategy

IEE Colloquium on `Advances in Control Systems for Electric Drives', 1995
The paper investigates the performance of three-phase cage rotor induction motor control systems based on direct torque control. Direct torque control is examined and it is found that this scheme is less complex and gives better control characteristics than the vector control methods.

Direct torque control of induction motors

IEE Colloquium on Vector Control and Direct Torque Control of Induction Motors, 1995
A direct torque control system for a variable speed induction motor drive consists of two hysteresis comparators, a selection table, a flux and torque estimator, and a PID speed controller. With this control structure, the drive performance can be significantly improved when compared to field oriented control.

Sensorless Vector and Direct Torque Control

1998
Abstract This is the first comprehensive book on sensor less high performance a.c. drives. It is essential reading for anyone interested in acquiring a solid background on sensor less torque-controlled drives. It presents a detailed and unified treatment of sensor less vector-controlled and direct-torque controlled drive systems.
