The research on constant tension control technique based on fuzzy multi models

通过分析焊丝层绕机的结构、特点以及在收线过程中影响焊丝张力的因素,建立张力系统数学模型,提出了基于线速度自适应的浮动辊位置反馈的控制策略;针对放线卷径变化对系统的影响,提出了模糊多模型的控制方案,设计了基于卷径模糊切换规则的多模型控制器。通过仿真实验证明能较好地满足预期控制要求。

Thorough the analysis of the structure, characteristic and the factors that effect the tension of the welding wire in the intertwine process, the models of tension system are established in the view of engineering. Floating - roller＇s position feedback control scheme based on the adaptive - self line speed is proposed. Considering the variation of the winding - diameter of the wheel of pay - off, a control strategy based on fuzzy multi - model is presented, and a multiple model controller using fuzzy winding - diameter switching regulation is designed. The simulation shows that the expected control performances are achieved.
