Improved Torque Control Performance in Direct Torque Control using Optimal Switching Vectors
International Journal of Power Electronics and Drive Systems (IJPEDS), 2015 This paper presents the significant improvement of Direct Torque Control (DTC) of 3-phases induction machine using a Cascaded H-Bidge Multilevel Inverter (CHMI). The largest torque ripple and variable switching frequency are known as the major problem founded in DTC of induction motor.

, 2013 The objective of this paper is to present a Direct Torque Control (DTC) algorithm for controlling system composed by two Permanent Magnet Synchronous Motors (PMSM) operating in parallel, fed by a single power inverter. In this system, it is expected that both motors will get the same speed even if they have different conditions of load torque.

Direct torque control of IM using PID controller
International Journal of Electrical and Computer Engineering (IJECE), 2020 Direct torque control "DTC" technique is one of a high performance control system of an AC motor drive, which was proposed after the vector oriented control scheme during the resent 25 years. It has been developed rapidly for its concise system scheme, transient and dynamic performance. The DTC mechanism consists of voltage vector selection table, two

Directional Singularity-Robust Torque Control for Gyroscopic Actuators
IEEE/ASME Transactions on Mechatronics, 2016 Gyroscopic actuation is appealing for wearable applications due to its ability to impart free moments on a body without exoskeletal structures on the joints. We recently proposed an unobtrusive balancing aid consisting of multiple parallel-mounted control moment gyroscopes (CMGs) contained within a backpack-like orthopedic corset.
