| 摘 要： | 本文利用涡流损耗分析的方法,推导了考虑纵向边端效应的直线感应电机动态数学模型。通过对直线电机控制特点的分析,设计了LIM矢量控制器。在此基础上,提出了一种以推力最大为目标的牵引直线感应电机推力优化控制方法。Matlab/Simulink仿真结果与直线电机牵引传动实验平台的实验结果表明,采用优化控制后直线电机在输入一定时能够提高输出推力,输入功率越小推力提高越明显,同时系统具有良好的调速性能,验证了本方案在牵引直线电机控制上的可行性。

| Abstract: | The dynamic LIM mathematical model inclusive of the longitudinal end-effect is derived by analysis of eddy current losses.The field orientation control scheme is developed through further analysis of the difference of linear motor and rotary motor control.On this basis,the linear induction motor traction thrust optimization control method is derived with the objective to acquire the maximum thrust.The Matlab/Simulink simulation results and experimental results of the linear motor traction and drive test pla... |
