摘要

基于PLC的倍捻机多电机控制系统由硬件部分和软件部分组成。硬件部分由可编程序控制器、步进驱动器、倍捻机多电机构成。步进驱动器、可编程序控制器、倍捻机多电机需要通过正确的逻辑连接起来。但是还起不到控制的作用，所以需要进行软件部分的设计。软件部分包括程序编制以及程序仿真。将此控制系统应用在导纱杆摇尺中，可以实现导纱杆摇尺工作的自动化。由于控制系统中没有位置检测装置，所以此系统属于开环控制。如果在控制系统中增加位置检测装置组成闭环系统，可以提高纱的加工精度。

Abstract

The multi-motor control system based on PLC consists of hardware and software parts. The hardware part is composed of programmable controller, step driver and multiple motor. Step drive, programmable controller, fold twist machine multiple motors need to be connected through the correct logic. But it does not have control yet, so you need to design the software part. The software part includes programming and program simulation. Applying this control system in the bar can be automated. Since there is no position detection device in the control system, this system is an open loop control. If a position detection device is added to the control system to form a closed-loop system, the processing accuracy of the yarn can be improved.
