A Constant Wire Tension Control System based on Improved PSO-PID in LS-WEDM

  • 摘要: 在慢走丝线切割走丝系统中,电极丝容易受到外界干扰和自身控制系统影响下,电极丝的张紧力会发生一定程度的波动,最大波动幅值可达50%,将导致导轮之间电极丝发生较大的挠曲变形和振动,严重影响加工工件的形位精度和表面质量。对电极丝进行受力分析,介绍改进型闭环控制电极丝走丝系统,设计恒张紧力闭环控制系统,运用改进型粒子群PID算法对电极丝进行在线恒张紧力控制。实验结果表明:本次设计的控制系统,具有高精度和实时性,电极丝张紧力波动控制在5%之内,对外界冲击载荷的修正时间约为4 s,且电极丝横向振动减少接近50%。
