摘要
针对普通PID算法在线材活套控制系统运用中存在的缺点,介绍了不完全微分PID算法的原理及设计方法,即在标准PID算法的基础上加入一阶惯性环节来构建不完全微分PID。通过合适的比例、积分、微分参数设置来改善活套系统的动态特性,达到稳定活套套高控制的目的。采用西门子STL语言编辑。实际使用效果表明,微分作用的引入具有超调小,调节过程快,能提高系统调节品质。
In view of the shortcomings of ordinary PID algorithm in the wire control system,this paper introduces the principle and design method of incomplete differential PID algorithm,namely,adding a first-order inertial link to the standard PID algorithm to build up a incomplete differential PID. Through appropriate proportion, integration and differential parameter setting, the dynamic characteristics of the loop system is improved to stabilize the control of the height of the loop.Siemens STL language editing is adopted.The result of actual use indicate that the introduction of differentiation helps to reduce overshoot,quicken adjustment process,and improve the system regulation quality.
