Design and Testing of Frequency-variable Control System for Elevator Driven by Linear Induction Motor

本文介绍了直线感应电动机驱动的电梯数字变频控制系统方案。基于圆筒型直线感应电动机驱动的电梯模型 ,采用微机控制方式 ,结合分布式控制理论 ,建立了以 DSP芯片 (TMS3 2 0 F2 4 0和单片机 MCS5 1为核心、基于 SVP-WM(空间矢量法 )的直线电机电梯全数字变频控制系统。在此基础上对模型进行了实验 。

This paper introduces a frequency- variable control system for el- evator driven by linear induction motor.Considering the elevator model driven by cylinder- type linear induction motor,the control system based on SVPWM is presented through adopting microcomputer control model and distribution control theory.It' s key is DSP slug TMS3 2 0 F2 4 0 and MCS5 1 .We have this elevator model tested,and the whole result is satisfactory.
