在分析异步电机数学模型和矢量控制原理的基础上,利用Matlab/Simulink软件,搭建了异步电机矢量控制仿真系统。采用模块化思想建立了磁链估计模块、MT-abc坐标变换模块和电流滞环控制模块,各模块与相应单元有机连接,构成了基于转子磁场定向的异步电机矢量控制仿真模型。仿真结果表明,该控制系统有效可行,对于开发和研究交流调速系统有一定的意义,可为异步电机矢量控制的研究提供参考。

Based on analyzing the mathematical model of asynchronous motor and the principle of vector control,this paper uses Matlab / Simulink software,and builts the asynchronous motor vector control simulation system. The simulation system which adopts the idea of modular established flux estimation module,MT- abc coordinate transformation module and hysteresis current control module,the organic connection of each module and the corresponding unit,constitute a simulation model of asynchronous motor vector control which is based on rotor flux orientation. The simulation results show that the control system is feasible and effective,has certain significance for the development and research of AC speed regulating system,which can provide reference for the study of asynchronous motor vector control.
