The Next Generation Motor Control Method: Direct Torque Control (DTC)

EPE Journal, 1995
AbstractDirect Torque Control (DTC) is the latest AC motor control method developed by ABB, In Direct Torque Control all switch changes are based directly on the electromagnetic state of the motor. Optimum switching is determined for every control cycle on a time level of 25 microseconds.

The next generation motor control method, DTC direct torque control

Proceedings of International Conference on Power Electronics, Drives and Energy Systems for Industrial Growth, 2002
Direct torque control (DTC) is the latest AC motor control method developed by ABB. ACS600 is the first application utilising DTC. DTC is a control method that embeds a motor and inverter together and controls them together in an optimal manner. In DTC, all switch changes are based directly on the electromagnetic state of the motor.

Novel direct torque control (DTC) scheme with fuzzy adaptive torque-ripple reduction

IEEE Transactions on Industrial Electronics, 2003
Investigations were carried out on a novel direct torque control system, which not only reduces the undesirable torque ripple by up to 98% by means of introducing a modulation between the selected active state and a zero state, but also maintains constant switching frequency.

A Modified Direct Torque Control (DTC) of Reluctance Synchronous Motor Sensorless Drive

Electric Machines & Power Systems, 2000
This paper presents a direct torque and flux sensorless control with (DTC) space vector modulation (SVM) for reluctance synchronous motor (RSM) drive. The flux, torque and speed estimators, hardware implementation and test results with DTC and DTC-SVM are presented and discussed.

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.

Controller design for direct torque controlled space vector modulated (DTC-SVM) induction motor drives

Proceedings of the IEEE International Symposium on Industrial Electronics, 2005. ISIE 2005., 2005
In this paper two different methods of PI controllers for direct torque controlled-space vector modulated induction motor drives have been studied. The first one is simple method based only on symmetric optimum criterion. The second approach takes into account the full model of induction motor including rotor voltage equation and uses root locus method.

A novel direct torque control (DTC) method for five-phase induction machines

APEC 2000. Fifteenth Annual IEEE Applied Power Electronics Conference and Exposition (Cat. No.00CH37058), 2002
In this paper, a direct torque control (DTC) scheme of a five-phase induction motor is developed. A novel DTC scheme is proposed, where fast torque response with low ripple in the stator PM and torque of five-phase induction motor can be achieved. In comparison with DTC for three phase induction motor, the five-phase DTC system has thirty-two space ...

Sensorless sliding mode direct torque control (DTC) of induction motor

Proceedings of the IEEE International Symposium on Industrial Electronics, 2005. ISIE 2005., 2005
A new approach to sensorless field oriented induction motor (IM) drive with a single loop control, which may correspond to DTC without a switching table, is presented. The proposed algorithm, presented in previous work by the author, is based on discrete-time sliding mode (SM) control theory and obtained by using two identical sliding surfaces with ...
