矢量控制与直接转矩控制是当前主要的两种电机变频调速控制方法，已在两相交流感应电机中得到 了应用。分析了两相不对称电机矢量控制和直接转矩控制原理以及两相三桥臂逆变器的SVPWM实现方法； 运用Matlab的Simulink建立了两相不对称交流感应电机矢量控制和直接转矩控制调速系统的仿真模型，并 对两种控制系统进行了仿真研究，给出了仿真波形，进行了特性比较． 关键词：两相电机；矢量控制；直接转矩控制；SVPWM；MATLAB；仿真(Vector Control and Direct Torque Control is currently the main method of frequency control of two motors, has been in two-phase AC induction motor has been applied. Analysis of asymmetric two-phase motor vector control and direct torque control principle and two-phase SVPWM inverter arm Bridge Implementation the use of Matlab in Simulink to establish a two-phase AC induction motor asymmetry of vector control and direct torque control modulation speed of system simulation models, and the two control system was simulated, the simulation waveform characteristics were compared. Key words: two-phase motor vector control direct torque control SVPWM MATLAB Simulation)
