| Abstract: | The basic principles of the direct torque control (DTC) were simply presented. For the six-corner stator flux curve,the circle stator flux curve and the eighteen-corner stator flux curve of fold angle control in the DTC system, the model and simulation were developed with the MATLAB/Simulink software. The results of the simulation and the characteristics of the DTC system with different stator flux curve were given. The reasonability and validity had been testified by the simulation results and this method offered the thoughtway for designing the actual asynchronous motor DTC system. |
