摘　　要：为了保证经编机在高速运转下送经量的恒定,运用当今经编机电子送经系统中最常见的送经原理,即利用反馈信号构建闭环控制系统,从而实现了同一送经量下以恒定线速度进行反馈控制,设计了一种基于高级精简机器指令(ARM)和现场可编程门阵列(FPGA)控制的高速经编机电子送经控制系统,并运用了PID控制理论。研究结果表明,该系统能实现经编机在高速运转下的稳定送经。In order to ensure warp knitting machine sent stably in the high-speed cases,the most common principle of constructing closed-loop system today was applied to achieve the task of feedback controlling on the condition of same amount of warp run-in and constant linear velocity.A kind of electronic warp let-off system based on advanced RISC machines（ARM） and field-programmable gate array（FPGA）-controlled was established.And the PID control theory was used.The results indicate that the system can achieve the goal of warp knitting machine stably working in the high speed cases.
