Research on Vector Control and Direct Torque Control in AC Motor Frequency Control

With the wide application of AC motor in modern social production,AC speed control system has become a research hotspot,and various frequency conversion speed control schemes have appeared one after another.As the two main AC motor frequency conversion control methods,vector control and Direct transfer control is widely used in practice.In this paper,the comparison between vector control and direct torque control is taken as the core,and the control principles,characteristics and applications of the two are analyzed and compared.At the same time,based on the analysis of the direct torque control principle,the simulation model of the direct torque control system is built based on the Simulink environment,and the corresponding simulation image is obtained.
