摘　　要：与两电平逆变器相比,三电平逆变器空间矢量图分区数量大大增加,因此,控制算法的复杂性也大大增加,基于Simulink的建模方法不利于控制算法的快速编写、修改和移植。提出一种基于Simulink和S-函数的复合建模方法,分析了三电平电驱动系统各个模块的原理,针对不同模块的特点,采用Simulink或者S-函数方法建立MATLAB模型,最后将所有模块连接起来进行仿真,仿真结果验证了所提建模方法的准确性。There are more areas in space vector diagram of three-level inverter than two-levelinverter. Therefore the control algorithm will be very complex. The modeling method based on Simulinkis not conducive for rapidly preparing,modifying and transplanting of control algorithm. A new methodbased on Simulink and S-function is proposed. The working principle of each module of the electricdrive system is analyzed. The model is established by using Simulink or S-function according to thecharacteristics of different modules of the three-level speed regulating system.Finaly,all modules areconnected to simulate. The simulation results verify the accuracy of the proposed modeling method.
