用Fuzzy二阶评判法研究织物性能与纱线之间的关系
织物性能 Fuzzy二阶评判法
2009/12/2
本文采用Fuzzy二阶评判法研究了织物的断裂和弹性指标与纱线之间的关系。该方法简便,接近实际,应用范围广。对研究成品与半成品之间的关系有一定的参考价值。
Fuzzy-PID复合控制在电子送经中的应用
电子送经 Fuzzy-PID
2009/10/20
为了满足织机的高速化和织造品种的多样化,对送经机构提出了更高的要求,需要准确控制送经机构的运动。而送经机构是一个典型的复杂、联动、时变、非线性、强干扰送经系统,传统的PID调节器不能取得令人满意的效果。针对传统的PID控制算法存在的缺陷,设计了一种Fuzzy-PID复合控制算法,并应用该算法面向SAURER400织机送经系统在MatLab中的Simulink进行仿真。结果表明,Fuzzy-PID复...

织机经纱张力Fuzzy-PID控制及其检测方法
SAURER400型织机 经纱张力 模糊控制 检测
2010/4/16
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...
