摘　　要：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。Vector control and direct torque control are the two main methods of variable frequency speed control, and they have been applied in two-phase AC induction motor. The theories of vector control and direct torque control and the operating principle of SVPWM control strategy used a two-phase three-leg inverter are analyzed. The simulation modles of two-phase asymmetric induction motor drive system with vector control and direct torque control are established by Matlab/Simulink. The two systems are studied and compared. The simulation waveforms are also given.
