基于前馈控制的经编机横移系统高速定位

经编机电子梳栉横移系统通常采用普通PID控制,难以满足梳栉横移高速、高响应和精准定位的要求.针对这一问题,在分析伺服电动机物理模型的基础上设计了由普通位置环、速度环和电流环组成的三闭环PID交流伺服控制系统,并在系统中引入电流环和速度环的前馈控制来提高梳栉的高速定位控制性能.通过MatLab软件的仿真测试和RSE4-1...

High-speed positioning of warp knitting machine shogging system based on feedforward control

In response to the difficulty of meeting the requirements of high speed,high response and accurate positioning of the electronic shogging system usually controlled by the conventional PID on warp-knitting machine,a three-closed-loop PID control system consisting of conventional position loop,speed loop and current loop was designed based on the analysis of physical model of servo motor.Introduction of the feedforward control of current loop and speed loop into the system improves the high-speed positioning ...
