Development of High Performance Control Systems for High Speed Web Handling Systems

DMI-9813213道森高速制造和运输薄网需要严格控制由材料不均匀、支承轧辊运动/偏心或空气动力激励引起的大振动。由于过度振动造成的腹板失效(即腹板断裂)浪费了材料和时间，因此采用主动振动控制来消除由振动引起的腹板断裂是很有必要的。这项研究的主要目标是：i)开发用于设计高性能控制器和相关机械执行器的纤网处理系统的数学框架，ii)开发用于轴向移动材料的新型纤网处理控制系统，这些材料需要大幅减振和/或需要精确的轴向速度跟踪以获得积极的期望速度分布，以及iii)通过实验验证理论结果和实时实施，将主动控制的纤网处理系统的应用推广到更广泛的应用。这项研究有望冲击控制理论(例如，可实现的性能改进的分布式模型控制器)、材料运输技术(例如，下一代高速机械)和其他交叉领域(例如，电缆系统、灵活的机器人机械手等)。它有可能为轴向运动的腹板状材料的振动控制创造全新的控制系统范例。

DMI-9813213 Dawson High-speed manufacture and transport of thin webs require tight control of the large vibration that can result from material non-uniformity, support roller motion/eccentricity, or aerodynamic excitation. Since failure of the web (i.e., web breaks) due to excessive vibration wastes material and time, the use of active vibration control for eliminating vibration-induced web breaks is well motivated. The primary objectives of this research are to: i) develop the mathematical framework for designing high-performance controllers and the associated mechanical actuators for web handling systems, ii) develop new web handling control systems for axial-moving materials that require large amplitude vibration reduction and/or require accurate axial-speed tracking for aggressive desired speed profiles, and iii) move the application of actively controlled web handling systems to more widespread use by experimentally verifying the theoretical results with real-time implementation. The research is expected to impact control theory (e.g., implementable performance improving distributed model controllers), material transport technology (e.g., next-generation high speed machinery), and other crosscutting areas (e.g., cable system, flexible robot manipulators, etc.). It has the potential of creating entirely new control system paradigms for the vibration control of axially-moving web-like materials.
