摘要:本课题设计了一套水针移动控制系统以解决造纸机网部用于纸机引纸和全幅定位的水针精准移动问题。基于变速双控制死区方法,控制水针移动和定位;通过控制水针移动的速度切换,配合设置双控制死区;采用水针降速的方式降低由水针移动引起的惯性误差,以达到精准控制水针定位的目的。结果表明,采用变速双控制死区方法,水针位移曲线变化平缓,最终停止时与水针设定位置的误差为0.8%,定位更加精确;且与变速单死区系统相比,水针移动反应时间缩短,为纸机水针精准位移控制提供有价值的参考。
Abstract:A trim squirt movement control system was designed to solve the problem of precise movement of the trim squirt used for paper threading and full-width positioning in the paper machine forming section. Based on the variable speed double dead zone method, the trim squirt movement and positioning were controlled. By controlling the switch of trim squirt movement speed, the double control dead zone was set in cooperation with it. The speed of the trim squirt was decreased to reduce the inertial error caused by the movement of the trim squirt to achieve the purpose of accurately controlling the positioning of the trim squirt. The results showed that the trim squirt displacement curve changed smoothly via variable speed double dead zone control method, and the error with the trim squirt setting position was 0.8% when it was stopped, which was more accurate. Compared with variable speed single dead zone system, the trim squirt movement response time was shortened, which provided a valuable reference for controlling the precise movement of trim squirt on the paper machine.
