摘要: 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,论文在分析伺服电机的物理模型基础上设计了由普通的位置环、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型高速经编机的上机实测表明,采用前馈PID控制时可有效提高控制系统的指令跟踪性能,与普通PID控制的电子横移系统相比,梳栉定位时间缩短2ms,取得了更高速的响应性和精准的定位效果。

Abstract: The electronic shogging system on warp-knitting machines usually controlled by the traditional PID, which is hard to achieve high speed, high response and accurate positioning. Based on the analysis of physical model of servo motor, the three-closed-loop PID control system composed of traditional position loop, speed loop and current loop was designed. And also, introducing the feedforward control of current loop and speed loop into the system to improve the high-speed positioning control performance of the bar. After that, with the simulation achieved by the Matlab and the testing on RSE4-1 high-speed warp knitting machine, the results indicated that of the signal tracking performance of control system can be improved effectively by using the feedward PID control. Compared with the electronic shogging system controlled by the traditional PID control, the positioning time was shortened 2ms, and the much faster response together with more accurate positioning were achieved.
