摘　　要：拉丝机卷绕张力是细丝拉丝生产过程中的重要因素。为解决钢丝拉丝过程中张力过大时易拉断、张力过小时卷绕效果差等问题,将基于PID控制算法的PLC技术应用到细丝拉丝机张力控制系统中,开展了张力产生原因及控制方法分析,建立了收卷速度与细丝拉力之间的关系及模型,提出了以PLC为核心控制器的张力控制方法;最后,基于Matlab Simulink对上述细丝张力控制系统进行了评价,并开展了相应的仿真试验。研究结果表明,该张力控制系统可以对拉丝机实现良好的控制效果,其响应快、超调小,具有较高的精度和稳定性。The winding tension of the wire drawing machine is an important factor in the process of drawing.In order to solve the problems of controlling tension of drawing machine, the tension control system of drawing machine based on PLC and PID control algorithms was investigated. After the analysis of tension causes and control, the relationship between the winding speed and tension was established. A method was presented to tension control system of drawing machine based on PLC. The tension control system of drawing machine was evaluated and tested on the Matlab Simulink. The experimental results show that the tension control system of drawing machine can achieve good effect. It has fast response, small overshoot, high accuracy and stability.
