Control of a Wind Turbine based on DFIG by Improved Direct Torque Control using Fuzzy Logic

Revue des Énergies Renouvelables
The capacity of doubly-fed induction generators (DFIGs) to regulate both active and reactive power makes them a well-liked option for wind turbines. Direct Torque Control (DTC) is a commonly employed method for managing DFIGs, but it has limitations such

Active Speed Compensation Method of Direct Torque Control System and Stability Analysis

Advances in Mechanical Engineering, 2015
By analyzing characteristics of the DTC (direct torque control) system in electrical driving system, a shortcoming of the classical DTC method is to point out that it is unable to decouple the mutual interference between torque and speed, so that when a ...
