叶梁缠绕机张力控制系统建模与设计

缠绕构件叶梁的横截面为矩形,缠绕过程中存在张力波动和切换点处张力突变现象.通过建立缠绕和放卷两大部分的数学模型,找出影响张力变化的几个关键因素,融合预测控制、系统辨识、动态补偿等控制算法,采用计算机+多轴运动控制器+张力控制器(IPC+PMAC+TC)的主从控制模式,有效避免了缠绕过程中切换点处的张力跳变问题.运行状况表明,该系统张力动态控制精度为±4％,满足企业的使用要求,取得了明显的经济效益和社会效益.     

Application of Clustering Fusion on Foreign Fibers Measure-Control System

According to the structure characteristics of foreign fibers detection system,the foreign fiber flow flux mathematical model and fiber detection system were designed.The information fusion clustering structure of foreign fiber flow flux was put forward.The data of the pressure difference,pressure,temperature,and density sensor which had impacted on flux were integrated and output by the Adaptive Resonance Theory-2(ART-2)network and BP network to clustering analysis of output space.The clustering control str...
