Dynamic Performance Enhancement of a Direct-Driven PMSG-Based Wind Turbine Using a 12-Sectors DTC
World Electric Vehicle Journal, 2022 This paper focuses on the performance analysis, modeling, and control of permanent magnet synchronous generator (PMSG)-based wind energy conversion. This work analyzes controllers for the machine-side converter (MSC) and grid-side converter (GSC) and ...

IEEE Transactions on Industrial Electronics, 2001
The authors propose to extend the direct torque control (DTC) concept. This extension concerns voltage-vector generation. Based on this, it is possible to generate any voltage vector by the space-vector modulation method and apply DTC strategy at the same time. Experimental results are carried out to validate the proposed approach.

An improved multilevel DTC drive
2001 IEEE 32nd Annual Power Electronics Specialists Conference (IEEE Cat. No.01CH37230), 2002An improved control algorithm for a multilevel DTC drive is proposed in the present paper. It allows avoidance of the demagnetisation phenomena at zero speed and reduction of the torque ripple without increasing the switching frequency. In particular, the reference torque time derivative is used with the aim of optimising the NPC converter voltage ...

Estimated dTc⧸dP and dTc⧸dσij for the Y1Ba2Cu3O7 superconductor
Physica C: Superconductivity, 1991Abstract For Y 1 Ba 2 Cu 3 O 7 , we estimated the critical-temperature pressure derivative d T c /d P and the three principal uniaxial compressive-stress derivatives d T c /dσ a , d T c /dσ b , d T c /dσ c . These estimates are useful because the measured values, especially d T c /dσ ij , show such strong disagreement. To estimate these

The property of ‘‘directional tone color,’’ especially characteristic of a violin [G. Weinreich, J. Acoust. Soc. Am. 101 (to be published)], consists of a directional radiation pattern which is a very strong function both of angle and of frequency.
