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., 2004This 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

Fuzzy logic direct torque control
ISIE'2000. Proceedings of the 2000 IEEE International Symposium on Industrial Electronics (Cat. No.00TH8543), 2002A brief review of the different induction motor drives is done and its reason of being such a high matter of interest is summarised. Next, the direct torque control (DTC) in induction motors with its fundamental principles and schemes is described. Once the DTC is described, its main drawbacks are introduced.

Direct Torque Control for Induction Motor
2021 International Conference on Digital Age & Technological Advances for Sustainable Development (ICDATA), 2021The 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

Direct torque control-frequency analysis
AMC'98 - Coimbra. 1998 5th International Workshop on Advanced Motion Control. Proceedings (Cat. No.98TH8354), 2002A DTC controller is developed, its characteristics compared with other scalar and vector control techniques based controllers. DTC behaviour is identified with analysis of main problems: variability of the voltage waveform supplied to the motor without pattern and without constant frequency.

Instantaneous Torque Estimation in Sensorless Direct-Torque-Controlled Brushless DC Motors
IEEE Transactions on Industry Applications, 2005A key issue in the direct torque control of permanent-magnet brushless dc motors is the estimation of the instantaneous electromagnetic torque, while sensorless control is often advantageous. A sliding-mode observer is employed to estimate the nonsinusoidal back-electromotive-force waveform, and a simplified extended Kalman filter is used to estimate ...

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.

Adaptive Controller for Induction Machine Direct Torque Control
2021 17th Conference on Electrical Machines, Drives and Power Systems (ELMA), 2021In this article is proposed a direct torque control of induction motor with additional control signal from adaptive controller. It‘s signal is summed with the those from the conventional PI regulator and the result is the reference torque signal. Using the created mathematical model, the modes of operation of an induction electric drive with adaptive ...
