The basic mathematical relationship of direct torque control is expounded. The direct torque control scheme of asynchronous motor is established in the entire speed regulation range of AC locomotive. The scheme is simulated under MATLAB environment. Simulation results show that the technology has excellent static and dynamic performance, which is very suitable for electric traction. The results of this study provide a reference for the design of AC drivetrain
