薄膜材料的绕组处理的适应失真压力的控制系统

摘要

薄膜材料的绕组处理是在一个高度非线性的动态系统中维持应力不变.提出一个为薄膜材料的绕组处理在不同摩擦锟供料速度下的适应模糊应力的控制系统.该提出的适应模糊应力的控制系统包括一个模糊应力控制器和一个适应调谐器.模糊应力控制器是主进度控制器,一个平移宽度的概念和变化模式技术被包括在模糊推论中以矫正模糊现象,而且只有一个参数因素需要被调整.为了对抗在实际应用中的不确定,一个失真压力的控制系统占据着简单控制框架,无震颤的,稳定跟踪性能和对不确定性的鲁棒的优势.与传统的比例积分应力控制方法相比较可提出的这种控制方法有显著的优势.%The winding process of the film materials is in a highly nonlinear dynamic system to maintain ten-sion at constant value. An adaptive fuzzy tension control (AFTC) architecture is proposed for winding process of the film materials under various feeding speeds at pinch rolls. The proposed AFTC architecture comprises a fuzzy tension controller and an adaptive tuner. The fuzzy tension controller (FTC) is the main tracking controller, in which a translation-width idea and sliding-mode technology are embedded into fuzzy inference engine to remedy chattering phenomena and only one parameter needs adjustment. To confront the uncertainties existed in practical applications, an adaptive tuner is added to adjust the parameter for further assuring robust and optimal performance. The winding process of the film materials with the AF- TC architecture possesses the salient advantages of simple control framework, free from chattering, stable tracking performance and robust to uncertainties. The advantages of the proposed control method are indi-cated in comparison with traditional proportional-integral tension control (PITC) method.
