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

Automatic Torque Controller for Torque Motors

Journal of the Society of Motion Picture and Television Engineers, 1952
The use of the automatic torque controller permits the full advantages of torque motors to be realized for film take-up and holdback duty without being handicapped by their inherent limitations when operated in the conventional manner.

Robust Torque Vectoring Control

IFAC Proceedings Volumes, 2014
Abstract An investigation on the robustness of a torque vectoring control based on an inverse disturbance observer architecture for a rear wheel driven vehicle with electric single wheel drives is presented within this contribution. To ensure robust control parameters, specifications for eigenvalues (Γ-stability) and bounds on weighted sensitivity ...

Direct Torque Control

2018
Abstract The fundamental principles of direct torque control (DTC) of permanent magnet synchronous (PMS) motors are presented in this chapter. The basic DTC system is then described. The operating limits of PMS machines under DTC are presented in terms of current limit, voltage limit, and flux linkage limit.

A new torque controller for Direct Torque Controlled Induction Machine drives

2008 12th International Middle-East Power System Conference, 2008
Hysteresis band control is one of the simplest and most popular techniques used in direct torque control (DTC) of induction machine drives. However the conventional fixed band hysteresis control has a variable switching frequency which causes serious problems in DTC.

Wide-speed direct torque and flux control of torque-controlled IPMSM drives

2012 IEEE Energy Conversion Congress and Exposition (ECCE), 2012
This paper proposes a voltage-limited finite-settling-step direct torque and flux control (FSS-DTFC) method with a constant switching frequency for torque-controlled interior permanent-magnet synchronous motors (IPMSMs). The proposed control law dynamically scales voltage vectors on the hexagonal voltage boundary to ensure maximum torque capabilities ...

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.
