| 摘 要： | 为了解决基于查表三电平DTC控制存在的电压矢量选择复杂性问题，将基于PI调节思想的DTC感应电机控制策略引入到三电平逆变器的控制中。有效降低了三电平逆变器DTC控制的复杂程度，便于系统实现。仿真结果表明这种基于PI调节的直接转矩控制方法具有便于中点电位控制、转矩响应快、转矩脉动低等优点。

| Abstract: | Control of a three-level inverter and control technique virtual synthesizing vectors based are demonstrated in detail, also, the method of vector selection is discussed in this paper. Then DTC strategy of induction motor based on PI regulating concept is utilized in control method of the three-level inverter, which contains such characteristics as convenient NP variation control, fast torque response and lower torque ripple. The simulation results validate the control strategies proposed. |
