摘要
本文在三相异步电机数学模型的基础上分析了矢量控制原理,建立了采用定子磁链定向矢量控制策略的异步电机矢量控制系统,采用U-I模型来观测电机定子磁链,并利用MATLAB软件对该矢量控制系统进行了建模仿真,仿真结果验证了所采用的控制策略的正确性和可行性。
This paper analyzed vector control principle based on the mathematics model of three – phase asynchronous motor,established asynchronous motor vector control system adopting stator flux oriented vector control strategy,and chose U-I model to realize observation of the motor stator flux. At last,the paper simulated the vector control system by MATLAB,the obtained simulation results have demonstrated the correctness and feasibility of control strategy being used.
