摘要
在分析三相异步电动机的数学模型及正弦波脉宽调制原理的基础上,根据异步电动机矢量控制理论,利用Matlab/Simulink软件建立了按转子磁链定向的异步电动机矢量控制系统仿真模型,并对转速、转矩和定子电流的动态特性进行了分析研究,给出了控制系统的仿真结果,验证了矢量控制是有效可行的。
Based on the analysis of the mathematical model of the three-phase asynchronous motor and sine pulse width modulation principle, According to the theory of asynchronous motor＇ s vector control, software is building simulation model of asynchronous motor＇ s vector control system according to the rotor flux in Matlab/Simulink, analysis dynamic characteristics of rotational speed, torque and stator current ,provided the simulation results of the control system, verify the vector control is effective and feasible.
