摘　　要：感应电动机传动系统是目前应用最广泛的交流传动系统,对其性能的计算机模拟和仿真具有重要的实际指导意义。结合MATLAB语言和环境,介绍在任意速参考坐标系下,基于感应电动机传动系统不同的控制策略和运行状态,导出其由状态变量方程描述的统一时域建模方法,详述仿真工具和方法的选择、逆变器的处理、及其完整的流程。对三相异步电动机的直接转矩控制(DTC)系统的仿真结果表明,该文所提出的仿真方法是有效和可行的。Performance simulation of induction motor drives is a significant work for they are the most widely used AC motor drives currently. Modeling and simulation technique of induction motor drives under MATLAB environment are introduced. State equations based on reference frame transformation theory are used as simulation model of drives operating under different control strategies. Problems about simulation method, procedure and power converter are discussed in detail. Satisfactory simulation results have been obtained in direct torque control （DTC）of induction motor. Thus, it shows that the method proposed in this paper is feasible and efficient.
