摘要
在分析异步电动机数学模型的基础上,利用Matlab/Simulink建立了按转子磁场定向的异步电动机矢量控制变频调速系统仿真模型,详细介绍了电流滞环PWM调节器、转子磁链观测模块的建立。仿真结果验证了建模方法的有效性。
This paper presents the Matlab/Simulink-based mathematical model of the rotor flux orientation vector control system of an AC Asynchronous motor. The modules of the hysteresis current PWM controller and of the rotor flux linkage observer are presented in detail. The simulation results are also given.
