摘要

着眼于讨论交流异步电机的矢量控制方法，在了解以及分析了交流异步电机的数学模型和调频控制原理的基础上，设计了一种电机的矢量控制方法以及建立模型并进行仿真。利用Matlab/Simulink的强大建模仿真功能，设计了各个功能模块，如：ACR模块、ASR模块，PI调节模块、坐标转换模块、磁通计算模块等。并且整合这些独立的模块成为一个矢量控制调速系统。仿真实验结果证明了该模型设计的合理性有效性。实验图表数据表明该建模方法能达到准确控制调速系统的要求。%This short essay come up with a modeling method about vector control system of AC asynchronous motor based on mathematical model of AC motor. Designed simulation model is made up by many independent function module, like: ACR module, ASR module, PI regulator module, Coordinate transformation module, Magnetic flux calculation module and so on.
