    1. Voltage vector control. The voltage vector control is mainly used in the single-phase coordinate system of asynchronous motor in the actual circuit control. The gall current in the circuit is processed by rectangular coordinate transformation. The control method of DC motor is simulated to achieve the control quantity of DC motor. However, the motor parameters will affect the system performance to a certain extent, leading to the vector rotation It is not conducive to the control of the overall effect.

    2. Direct torque control. Direct torque control (DTC) technology was proposed in 1985. The development of this technology has a very important balance effect on the loopholes in vector control. Moreover, the dynamic and static characteristics of the technology are relatively high, and the structure is relatively simple. With the continuous improvement of related technology research, its application in practical application and application effect are also improving. Its application in traction AC drive of high-power electric locomotive does not need to deal with AC motor, so the transformation mode is simpler and the application range is wider.
