摘　　要：设计了一套圆筒形直线感应电动机驱动的电梯全数字变频控制系统 ,对其进行了试验。针对此试验结果和此电动机本身固有的纵向边缘效应 ,提出了一种方法并建立了此电动机的数学模型 ,对边缘效应进行补偿 ,在此基础上设计了基于速度环单神经元PI调节的以转子磁场定向的矢量控制系统。仿真结果表明 ,此系统能大大提高电梯运行性能。This paper introduces a frequency variable control system for elevator driven by linear induction motor,and this elevator has been tested.In this system,chip TMS320F240 are used which is special for motor control.Considering the speed tracking effect is not so satisfactory and the intrinsic end effect of linear induction motor,we present a method for constructing the mathematical model of this motor to compensate the end effect,and develop a field oriented control system based on single neuron PI for linear induction motor driven elevator,then have this model simulated and tested.The results are provided to verify that this mathematical model is effective and the control algorithm is robust against parameters variation and load change.
