摘要
采用转子磁链定向矢量控制方法,对九相感应电机矢量控制系统的转矩动静态响应进行了研究。针对应用传统的谐波电流开环控制策略时定子电流谐波含量较大的问题,使用了谐波电流闭环控制策略以抵制各高次谐波对定子电流的影响。以一台九相集中整距绕组感应电机为例,在MATLAB的Simulink工具箱中搭建了完整的九相感应电机矢量控制系统模型。仿真结果表明,系统可以有效抑制定子的谐波电流,且具有较好的动态性能。
Based on the rotor field oriented control method, the dynamic and static torque response of a ninephase induction motor vector control system was studied. To solve the problem of high harmonic content in the stator current in the conventional harmonic currents open-loops control strategy, the harmonic currents closed-loops control method was used to resist the higher harmonic currents＇ s effect on the stator currents . Taking a nine phase concentrated winding induction motor for example, a complete nine-phase induction motor vector control system model was built in MATLAB/Simulink toolbox. The simulation results show that the system can effectively restrain the stator harmonic current, and has good dynamic performance.
