摘　　要：交流电机磁场定向矢量控制变频调速原理是电气自动化专业高年级及研究生学习的一个难点。基于同步旋转dq坐标系研究了异步电动机数学模型和矢量控制调速原理,Matlab仿真异步电动机转子磁场定向矢量控制调速实验结果表明实现了模拟直流电动机磁链电流和转矩电流的解耦控制,达到了高性能调速,从而直观生动地引导学生深刻理解交流电机矢量控制变频调速原理,提高了教学质量。Students on electrical automation majors found it difficulty to master principle of the ac mo- tor magnetic field oriented vector control. Based on the synchronous rotating dq coordinate, the asyn- chronous motor mathematical model and vector control speed regulation principle were discussed and speed control experiment was given on Matlab plat. Results showed that high performance control had been achieved by simulating dc motor of excitation current and torque current decoupling. It was intui- tive and vividly to guide students to understand the ac motor vector control variable frequency speed control principle and improve teaching quality.
