摘　　要：建立了三相异步电机在二相任意坐标系下的仿真模型,利用开关函数概念设计了一种实用的三相电压型逆变器仿真模型。给出用MATLAB/SIMULINK实现这种异步电机调速系统通用仿真模型的模块化设计步骤。该调速系统模型简捷、方便。文中对V/f控制下电机空载起动及突加负载进行了动态仿真,结果表明该模型的有效性,为研究不同控制策略下调速系统的动态性能仿真奠定基础。A general simulation model of the three-phase asynchronous machine is proposed in two-axis theory of arbitrary reference frame.This model is controlled by the three-phase voltage-source inverter,which is established by the switching function concept.The actual implementation of the asynchronous machine drive model is explained in detail with the help of MATLAB/SIMULINK and the drive circuit can be designed easily.The dynamic simulation of V/f control mode has been carried out under free acceleration and variable loads.Results verify the effectiveness of the drive model,which lays the foundation for the study of the dynamic performance of the asynchronous machine drive sith different control strategies.
