Direct torque control

 Direct Torque Control (Direct Torque Control, DTC), the text of the abroad some also called Direct self - Control, DSC, literal translation for Direct self Control, the concept of Direct self Control for Torque as the center for www.dongfeng- motor.com integrated Control, not only to Control the Torque, also used for the amount of flux linkage Control and flux linkage Control. The difference between the direct torque control and vector control is that it is not by controlling current, flux amount of indirect spare parts torque control, but the torque directly accused of quantity control, as the essence of which is using space vector analysis method, with the stator magnetic field orientation, the motor electric stator flux and electromagnetic torque in direct control. In 1985 Germany's ruhr university DiPu brock (m. epenbrock) professor is presented based on the first hexagon and round flux trajectory of the Direct torque control theory, he is called Direct self - control - DSC. This method does not need complex coordinate transformation, but directly on the motor fan cover stator coordinate computing the size of the torque and flux of the mold, and by direct tracking of flux and torque PWM pulse width modulation and high dynamic performance of the system.
