Research on the Switching Algorithm of Voltage Vectors in the Direct Torque Control System

The study of algorithms switching voltage vectors, provides new possibilities in asynchronous motors with direct torque control. The article presents two methods of changing the angle of the voltage sector containing the voltage vector, in order to increase the speed of torque response and the flow of values, when the reverse is large or very small, will improve the quality of the control system. This will improve the quality of the electric drive at start-up and change the speed of the motor. At the same time, there are two new selector tables for flexible installers in the engine torque management options. The simulation result in Matlab ensures the quality of this method. The performance is shown in the stator stream, electromagnetic torque and in the speed of the motor in accordance with the set values.
