摘　　要：以双边长初级短次级直线感应电动机为研究对象,根据样机的实际结构分析推导了电机的数学模型。直线电机存在由于铁心开断而引起的端部效应,在采用矢量控制策略时,需要对基于旋转感应电动机的矢量控制策略进行修正,建立了基于MATLAB/Simulink的系统模型,进行了直线感应电动机矢量控制的仿真研究,验证了控制方案的可行性与正确性。在理论分析和仿真验证的基础上,设计了基于TMS320F2812的全数字矢量控制系统的控制系统硬件电路,进行了系统实验,实现了电机定位、往返运动等功能。A mathematical analysis of a doubled-sided, short secondary linear induction motor was made, and an equivalent circuit and the establishment of the mathematical model were given out. Because of the dynamic vertical end effect of the linear induction motor, the end effect function was added according to vector control theory of the induction motor. The model of the control system based on MATLAB/Simulink was established. And much study about vector control was done to verify the feasibility and correctness of control system model mentioned. The program of the vector control system of linear induction motor based on TMS320F2812 was compiled, and the relevant experiments and analysis were done. The location, reciprocating motion and other functions were mainly achieved.
