Design and Test of New Control System of Two-For-One Twister Based on Multi-Motor Drive

在分析倍捻机控制系统总体框架的基础上,设计了以ARM为控制核心的多电机传动的倍捻机新型控制系统。研究交流电机、步进电机和伺服电机的控制方式,并设计硬件电路以实现它们之间的协调工作,使倍捻机达到工艺要求。设计倍捻机防叠防凸控制算法,使纱线卷绕达到了良好的成型效果。测试结果表明:该控制系统操作简单、控制精度高、实时性好,达到了设计要求。

This paper designs a new control system of two-for-one twister in multi-motor drive mode with ARM as control core based on the analysis on the general framework of two-for-one twister; studies the control mode of AC motor, stepping motor and servo motor and designs hardware circuit to realize their cooperation and making the two-for-one twister reach the work requirement of process design; and designs an algorithm of fold and protrusion prevention of two-for-one twister, making yarns have good forming effects. The experimental result shows that this control system has a simple operation, high control accuracy and good real-time performance, reaches the design requirement and has a good work performance.
