摘　　要：为更好地控制经纱张力,防止因波动过大对织物质量产生负面影响,在论述现有经纱张力控制方法的基础上,提出采用Fuzzy-PID控制方法的合理性。根据实际经验给出简化的模糊控制规则表。面向SAURER400型织机送经系统进行试验,通过计算机、应用软件及传感器等手段及自行搭建的测试系统,对经纱的张力变化进行在线检测。实验结果表明:模糊控制经纱张力对抑制张力峰值,改善张力的特征值是行之有效的;在织造过程中降低了经纱断头率,下机织物的稀密路得到了改善。In order to improve the warp tension control and prevent too much variations which result in negative impact on the fabric quality, Fuzzy-PID controller was used to control the warp tension based on researches on the existing control methods of warp tension. And some warp control rules are given according to researchers＇ experience. On-line testing of the warp tension is affected by a test system consisting of the computer, software, and sensor and so on. The experiment is carried out on SAURER400 loom. The resuhs show that it is effective in controlling the warp tension for restraining tension crest value and reducing warp end breakage, not only reducing tension variations, but also improving tension discrete index. And the starting marks of the fabric have been decreased significantly.
