摘　　要：首先介绍了考虑端部效应后直线感应电机的动态数学模型,接着推导了其在两相静止坐标系下的状态方程,并采用Matlab C-MEX S函数编写了直线感应电机的动态仿真模型。在此基础上讨论了基于DSP的直线感应电机的矢量控制方案,建立了在Matlab/Si mulink环境下的仿真模型,并进行了详细的仿真分析。然后在直线电机牵引综合实验线上进行实验。实验和仿真结果表明采用矢量控制的直线感应电机变频调速系统具有较好的静、动态性能,是一种优越的控制策略。An equivalent circuit model in the rotor flux oriented frame was developed by adding the end erect function at first. The stationary equation in two-phase synchronous reference frame of LIM was calculated and a new C-MEX S-function simulation model of linear induction motor was constituted. Based on this, the vector eontrol scheme was discussed and simulated with Matlab/Simulink based on the mathematical model. Then the experiment was done on the linear induction motor traction comprehensive test line. The experiment results show that this control system has good static and dynamic performance.
