摘要
在矢量控制理论的基础上,从异步电动机的数学模型出发,介绍了一种交流异步电动机按转子磁场定向的矢量控制系统。利用Matlab/Simulink搭建了该系统仿真模型,对仿真中转速突变及负载突变后的波形作了分析,表明所建立的调速系统具有良好的动态性能,实现了系统的解耦控制,仿真结果验证了该模型的正确性和有效性。
Based on vector control theory, a kind of vector control system by asynchronous motor rotor fieldoriented which according to the mathematical model of asynchronous motor is introduced. This system simulation model is built by Matlab/Simulink. The waveform of speed mutation and load mutations are analyzed. The results show that the speed regulation system has good dynamic performance and realizes decoupling control of the system. The simulation result testifies the correct and effective of this model.
